`
`(1) Grounds of Rejection to be Reviewed on Appeal
`
`Every ground of rejection set forth in the Office action dated 12/04/2018 from
`
`which the appeal is taken is being maintained by the examiner except for the grounds of
`
`rejection (if any) listed under the subheading “WITHDRAWN REJECTIONS.” New
`
`grounds of rejection (if any) are provided under the subheading “NEW GROUNDS OF
`
`REJECTION.”
`
`Claim Rejections - 35 USC § 103
`
`This application currently names joint inventors. In considering patentability of the
`
`claims the examiner presumes that the subject matter of the various claims was
`
`commonly owned as of the effective filing date of the claimed invention(s) absent any
`
`evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to
`
`point out the inventor and effective filing dates of each claim that was not commonly
`
`owned as of the effective filing date of the later invention in order for the examiner to
`
`consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2)
`
`prior art against the later invention.
`
`The following is a quotation of 35 U.S.C. 103 which forms the basis for all
`
`obviousness rejections set forth in this Office action:
`
`A patent for a claimed invention may not be obtained, notwithstanding that the claimed
`invention is not identically disclosed as set forth in section 102 of this title, if the differences
`between the claimed invention and the prior art are such that the claimed invention as a whole
`would have been obvious before the effective filing date of the claimed invention to a person
`having ordinary skill in the art to which the claimed invention pertains. Patentability shall not
`be negated by the manner in which the invention was made.

`
`Claims 1-6 and 10-12 are rejected under 35 U.S.C. 103 as being
`
`unpatentable over Yoshida (US 5,735,993) in view of Chen et al (US 5,226,967),
`
`Yoshida et al (US 5,690,781), and Ghanbari (US 5,982,100).
`
`Regarding claim 1:
`
`Yoshida’993 teaches a plasma processing apparatus (plasma processing
`
`apparatus) [fig 7 & col 5, lines 59-61], comprising: a vessel which comprises a reaction
`
`chamber (vacuum reaction vessel, 10), wherein atmosphere within the reaction
`
`chamber (10) is capable of being depressurized (via vacuum) [fig 7 & col 4, lines 12-27];
`
`a lower electrode (lower electrode, 11) which supports an object to be processed
`
`(sample, 27) within the reaction chamber (vacuum reaction vessel, 10) [fig 7 & col 4,
`
`lines 3-11]; a dielectric member (dielectric portion, 2) which comprises a first surface
`
`(top surface of 2) and a second surface (bottom surface of 2) opposite to the first
`
`surface (top surface of 2) [fig 7 & col 5-6, lines 59-4], and which closes an opening of
`
`the vessel (dielectric plate 2 which constitutes part of a vacuum reaction vessel 10)
`
`such that the first surface (top surface of 2) opposes an outside of the reaction chamber
`
`(area above 10) and the second surface (bottom surface of 2) opposes the object to be
`
`processed (sample, 27) [fig 7 & col 3, lines 52-63]; and a coil (spiral coil, 1) which
`
`opposes the first surface of the dielectric member (top surface of 2), and which
`
`generates plasma (causes generation of a plasma) within the reaction chamber (10) [fig
`
`7 & col 4, lines 12-27].
`
`Yoshida’993 does not teach the dielectric member has a groove having an
`
`annular shape and formed on the surface of the dielectric member, and wherein a depth
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 5
`
`of the groove increases stepwise from an inner circumference of the groove toward an
`
`outer circumference of the groove.
`
`Chen teaches a dielectric member (window, 18) has a groove having an annular
`
`shape (surface around thickened central portion) and formed on the surface of the
`
`dielectric member (bottom surface of 18), and wherein a depth of the groove (surface
`
`around thickened central portion) increases stepwise (series of steps) from an inner
`
`circumference of the groove (window portion, 183) toward an outer circumference of the
`
`groove (window portion, 181) [fig 7 & col 6, lines 23-62].
`
`Yoshida’993 and Chen are analogous inventions in the field of plasma
`
`processing apparatuses. It would have been obvious to one skilled in the art before the
`
`effective filing date to modify the dielectric member of Yoshida’993 with a groove, as in
`
`Chen, to achieve substantially uniform ion current density across the diameter of the
`
`substrate [Chen — col 5-6, lines 67-8].
`
`Yoshida’993 modified by Chen does not teach the dielectric member has a
`
`groove formed in the first surface of the dielectric member, and wherein at least a part
`
`of the coil is disposed in the groove, and the part of the coil disposed in the groove is a
`
`peripheral part of the coil and a remaining part of the coil disposed outside of the
`
`groove.
`
`Yoshida’781 teaches a dielectric member (dielectric plate, 4) has a groove
`
`(surface around upwardly convex shape) formed in the first surface of the dielectric
`
`member (top surface of 4), and wherein at least a part of the coil (spiral coil, 2) is
`
`disposed in the groove (provided to conform along the surface around convex shape),
`
`and the part of the coil disposed in the groove is a peripheral part of the coil (periphery
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 6
`
`of 2 provided along the surface around convex shape) provided and a remaining part of
`
`the coil disposed outside of the groove (remainder of 2 provided above convex shape)
`
`[fig SB & col 4-5, lines 56-6].
`
`Modified Yoshida’993 and Yoshida’781 are analogous inventions in the field of
`
`plasma processing apparatuses. It would have been obvious to one skilled in the art
`
`before the effective filing date to modify the groove of modified Yoshida’993 to be
`
`formed in the top surface of the dielectric member, as in Yoshida’781, to make
`
`maintenance of the reaction chamber easier while achieving the same effect of a
`
`uniform processing rate across the diameter of the substrate [Yoshida’781 — col 4-5,
`
`lines 61 -6].
`
`Yoshida’993 modified by Chen and Yoshida’781 does not teach a distance
`
`between the peripheral part of the coil and the dielectric member is shorter than a
`
`distance between a remaining part of the coil and the dielectric member.
`
`Ghanbari teaches a distance between the peripheral part of the coil and the
`
`dielectric member is shorter than a distance between a remaining part of the coil and
`
`the dielectric member (segments of lesser radii are arranged to reside further away from
`
`the dielectric plate than segments of greater radii) [fig 1 & col 2, lines 44-63 and col 3,
`
`lines 39-50].
`
`Modified Yoshida’993 and Ghanbari are analogous inventions in the field of
`
`plasma processing apparatuses. It would have been obvious to one skilled in the art
`
`before the effective filing date to modify the coil of modified Yoshida’993 with the coil
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 7
`
`configuration of Ghanbari to vary the field configuration within the chamber to
`
`accommodate different size and shape workpieces [Ghanbari - col 2, lines 44-63].
`
`Regarding claim 2:
`
`Modified Yoshida’993 teaches a center of the groove (surface around thick part
`
`at the center) is substantially overlapped with a center of the coil (coil to be axially
`
`symmetrical about the center of the reaction chamber) as viewed from a direction
`
`perpendicular to the first surface of the dielectric member (direction depicted in fig BA-
`
`BB) [Yoshida’781 - fig 3A-BB & col 2, lines 6-38 and col 4, lines 22-41].
`
`Regarding claim 3:
`
`Yoshida’993 modified by Chen does not teach the coil comprises a conductor
`
`having a length L and extending from a first end on a center side to a second end on an
`
`outer peripheral side, wherein the conductor comprises a center side portion having a
`
`length 0.5L extending from the first end and a remaining outer peripheral side portion,
`
`and wherein a ratio of the center side portion disposed within the groove is smaller than
`
`a ratio of the remaining outer peripheral side portion disposed within the groove.
`
`Yoshida’781 teaches a coil (spiral coil, 2) comprises a conductor having a length
`
`L (length of coil from center to outer peripheral side — the radius of 2) and extending
`
`from a first end on a center side (center of reaction chamber) to a second end on an
`
`outer peripheral side (outer right side of 2) [fig 5B & & col 2, lines 6-38 and col 4-5, lines
`
`56-6], wherein the conductor comprises a center side portion (center portion of radius of
`
`2) having a length 0.5L (length of coil from center to 0.5 the distance to outer peripheral
`
`side) extending from the first end and a remaining outer peripheral side portion (halfway
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 8
`
`between center and outer right side of 2) [fig SB & & col 2, lines 6-38 and col 4-5, lines
`
`56-6].
`
`Yoshida’781 does not specifically disclose “a ratio of the center side portion
`
`disposed within the groove is smaller than a ratio of the remaining outer peripheral side
`
`portion disposed within the groove” but teaches a ratio of the center side portion to the
`
`remaining outer side portion (d/D) is a result-effective variable [fig 3A-3D & col 4, lines
`
`22-41].
`
`It would have been obvious to a person of ordinary skill in the art before the
`
`effective filing date to discover the optimum range for the ratio of the center side portion
`
`to the remaining outer side portion through routine experimentation in order to discover
`
`the optimum ratio for reducing the induction field at the center to achieve a uniform ion
`
`current density {fig 3A-3D & col 4, lines 22-41]. Absent a showing of criticality with
`
`respect to the ratio of the center side portion to the remaining outer side portion, it has
`
`been held that discovering an optimum value of a result effective variable involves only
`
`routine skill in the art [MPEP 2144.05].
`
`Modified Yoshida’993 and Yoshida’781 are analogous inventions in the field of
`
`plasma processing apparatuses. It would have been obvious to one skilled in the art
`
`before the effective filing date to modify the groove of modified Yoshida’993 with the
`
`dimensions of Yoshida’781 to achieve a uniform processing rate across the diameter of
`
`the substrate [Yoshida’781 — col 2, lines 6-38].
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Regarding claim 4:
`
`Page 9
`
`Yoshida’993 modified by Chen and Yoshida’781 does not specifically disclose a
`
`winding density of the coil in the center side portion is smaller than that of the remaining
`
`outer peripheral side portion.
`
`Ghanbari does not specifically disclose “a winding density of the coil in the center
`
`side portion is smaller than that of the remaining outer peripheral side portion” but
`
`teaches the winding density is a result-effective variable [fig 2 & col 3, lines 51 -65].
`
`It
`
`would have been obvious to a person of ordinary skill in the art before the effective filing
`
`date to discover the optimum range for the winding density through routine
`
`experimentation in order to modify the field configuration within the plasma chamber [fig
`
`2 & col 3, lines 51 -65]. Absent a showing of criticality with respect to the winding
`
`density, it has been held that discovering an optimum value of a result effective variable
`
`involves only routine skill in the art [MPEP 2144.05].
`
`Modified Yoshida’993 and Ghanbari are analogous inventions in the field of
`
`plasma processing apparatuses. It would have been obvious to one skilled in the art
`
`before the effective filing date to modify the coil of modified Yoshida’993 with the
`
`winding density of Ghanbari to adjust the coil to produce a more uniform plasma
`
`[Ghanbari — col 3, lines 51 -65].
`
`Regarding claims 5-6:
`
`Yoshida’993 teaches an electrode pattern (1 a/1 b) and an insulation film (portion
`
`of 2 surrounding 1a/1 b) which covers the electrode pattern (1a/1 b), which are formed on
`
`the second surface of the dielectric member (bottom surface of 2) [fig 7 & col 5-6, lines
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 10
`
`59-4]; wherein the electrode pattern (1a/1 b) comprises an electric heater (heater, 1b)
`
`which heats the dielectric member (dielectric portion, 2) [fig 7 & col 5-6, lines 59-4].
`
`Yoshida’993 does not specifically disclose that the insulation film and dielectric
`
`member are separate structures.
`
`It would have been obvious to one having ordinary
`
`skill in the art before the effective filing date to separate the dielectric member into two
`
`structures (dielectric member and insulation film), since it has been held that making a
`
`formerly integral structure separable involves only routine skill in the art [MPEP
`
`2144.04].
`
`Regarding claim 10:
`
`Modified Yoshida’993 teaches the part of the coil (spiral coil, 2) disposed in the
`
`groove (surface around upwardly convex shape) follows a bottom shape of the groove
`
`(provided to conform along the surface around convex shape) [Yoshida’781 - fig 5B &
`
`col 4-5, lines 56-6].
`
`Regarding claim 11:
`
`Modified Yoshida’993 teaches a maximum depth of the groove (surface around
`
`thickened central portion) is in a range from 0.25T to 0.45T, where T is a thickness of
`
`the dielectric member before forming the groove (1 :6 to 1 :1.5 = 0.17T to 0.67T) [Chen -
`
`fig 7 & col 6, lines 9-22].
`
`In a case where the claimed ranges overlap or lie inside ranges disclosed by the
`
`prior art a prima facie base of obviousness exists. See In re Wertheim, 541 F.2d 257,
`
`191 USPQ 90 (CCPA 1946), and MPEP 2144.05.
`
`Regarding claim 12:
`
`Modified Yoshida’993 teaches an area of the dielectric member in which the
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 11
`
`groove (surface around thickened central portion) is formed is in a range from 0.028 to
`
`0.58, where 8 is an area of the first surface of the dielectric member (diameter of 3 to 4
`
`inches of a total diameter of 9 to 10 inches = Tr*(3/2)2: Tr*(1O/2)2 to Tr*(4/2)2: 1'r*(9/2)2 =
`
`7.1 :78.5 to 12.6:63.6 = 0.098 to 0.28) [Chen - fig 7 & col 6, lines 43-55].
`
`In a case where the claimed ranges overlap or lie inside ranges disclosed by the
`
`prior art a prima facie base of obviousness exists. See In re Wertheim, 541 F.2d 257,
`
`191 U8PQ 90 (CCPA 1946), and MPEP 2144.05.
`
`Claims 7-9 are rejected under 35 U.S.C. 103 as being unpatentable over
`
`Yoshida (US 5,735,993) in view of Chen et al (US 5,226,967), Yoshida et al (US
`
`5,690,781), and Ghanbari (US 5,982,100) as applied to claims 1-6 and 10-12 above,
`
`and further in view of Collins et al (US 6,361,644).
`
`The limitations of claims 1-6 and 10-12 have been set forth above.
`
`Regarding claim 7:
`
`Modified Yoshida’993 teaches the electrode pattern (1 a/1 b) comprises a plate
`
`electrode (metallic plate, 1a) [Yoshida’993 - fig 7 & col 5-6, lines 59-4].
`
`Modified Yoshida’993 does not teach the plate electrode is capacitively coupled
`
`to the plasma when the plate electrode is supplied with radio frequency power.
`
`Collins teaches a plate electrode (conductive backplane, 400) is capacitively
`
`coupled (parallel plates) to the plasma when the plate electrode (400) is supplied with
`
`radio frequency power (via RF generator) [fig 25A & col 1, lines 12-16 and col 20-21,
`
`lines 66-19].
`
`Modified Yoshida’993 and Collins are analogous inventions in the field of plasma
`
`processing apparatuses. It would have been obvious to one skilled in the art before the
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 12
`
`effective filing date to modify the plate electrode of modified Yoshida’993 to be
`
`capacitively coupled to the plasma, as in Collins, to combine the advantages of
`
`inductive and capacitive coupling in a single reactor [Collins — col 5, lines 33-44].
`
`Regarding claim 8:
`
`Modified Yoshida’993 teaches a first electrode pattern (metallic plate, 1a) and a
`
`first insulation film (portion of 2 surrounding 1a) which covers the first electrode pattern
`
`(1 a), which are formed on the second surface of the dielectric member (bottom surface
`
`of 2) [Yoshida’993 - fig 7 & col 5-6, lines 59-4], a second electrode pattern (heater, 1b)
`
`and a second insulation film (portion of 2 surrounding 1b) which covers the second
`
`electrode pattern (1 b), which are formed on a surface of the first insulation film opposite
`
`to the dielectric member (portion of 2 surrounding 1a) [Yoshida’993 - fig 7 & col 5-6,
`
`lines 59-4], wherein one of the first and second electrode patterns (1 a/1 b) comprises an
`
`electric heater (heater, 1b) which heats the dielectric member (dielectric portion, 2), and
`
`wherein the other of the first and second electrode patterns (1a/1 b) comprises a plate
`
`electrode (metallic plate, 1a) [Yoshida’993 - fig 7 & col 5-6, lines 59-4].
`
`Modified Yoshida’993 does not specifically disclose that the first insulation film,
`
`second insulation film, and dielectric member are separate structures.
`
`It would have
`
`been obvious to one having ordinary skill in the art before the effective filing date to
`
`separate the dielectric member into three structures (dielectric member and first/second
`
`insulation films), since it has been held that making a formerly integral structure
`
`separable involves only routine skill in the art [MPEP 2144.04].
`
`Additionally, modified Yoshida’993 does not teach the plate electrode is
`
`capacitively coupled to the plasma within the reaction chamber when the other of the
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 13
`
`first and second electrode patterns is supplied with radio frequency power.
`
`Collins teaches a plate electrode (conductive backplane, 400) is capacitively
`
`coupled (parallel plates) to the plasma within the reaction chamber when the other of
`
`the first and second electrode patterns (400) is supplied with radio frequency power (via
`
`RF generator) [fig 25A & col 1, lines 12-16 and col 20-21, lines 66-19].
`
`Modified Yoshida’993 and Collins are analogous inventions in the field of plasma
`
`processing apparatuses. It would have been obvious to one skilled in the art before the
`
`effective filing date to modify the plate electrode of modified Yoshida’993 to be
`
`capacitively coupled to the plasma, as in Collins, to combine the advantages of
`
`inductive and capacitive coupling in a single reactor [Collins — col 5, lines 33-44].
`
`Regarding claim 9:
`
`Modified Yoshida’993 teaches the electric heater (heater, 1b) as a whole is
`
`disposed within the plate electrode (metallic plate, 1a) as viewed from a direction
`
`perpendicular to the second surface of the dielectric member (same geometry)
`
`[Yoshida’993 - fig 2, 7 & col 5-6, lines 59-10].

`
`(2) Response to Argument
`
`Page 14
`
`(A) Applicant argues that the references, alone or in combination, do not
`
`disclose, teach, or render obvious the limitation “wherein a distance between the part of
`
`the coil disposed in the groove and the dielectric member is shorter than a distance
`
`between a remaining part of the coil disposed outside of the groove and the dielectric
`
`member”. Specifically, Ghanbari only teaches that a distance between the peripheral
`
`part of the coil and the dielectric member is shorter than a distance between the central
`
`part of the coil and the dielectric member. Since Ghanbari does not show any groove,
`
`Ghanbari fails to teach the limitation above. The distance comparison in this limitation
`
`depends upon how deep the groove is and where the groove is located. Since Ghanbari
`
`fails to show how deep the groove is and where the groove would be located if the
`
`groove was created on the dielectric member of Ghanbari, Ghanbari in combination with
`
`Yoshida’993 modified by Chen and Yoshida’781 would not make the claimed invention
`
`obvious.
`
`In response, examiner maintains that the combination of references render this
`
`limitation obvious. The test for obviousness is not whether the claimed invention must
`
`be expressly suggested in any one or all of the references. Rather, the test is what the
`
`combined teachings of the references would have suggested to those of ordinary skill in
`
`the art. See In re Keller, 642 F.2d 413, 208 USPQ 871 (CCPA 1981). As set forth in the
`
`advisory action dated 12/04/2018:
`
`Yoshida'993 modified by Chen and Yoshida'781 teaches the part of the coil
`
`disposed in the groove is a peripheral part of the coil and a remaining part of the coil
`
`
`
`Application/Control Number: 15/714,231
`Art Unit: 1718
`
`Page 15
`
`disposed outside the groove is a central part of the coil [Yoshida'781 - fig SB & col 4-
`
`5, lines 56-6].
`
`Ghanbari teaches a distance between the peripheral part of the coil and the
`
`dielectric member is shorter than a distance between the central part of the coil and the
`
`dielectric member (segments of lesser radii are arranged to reside further away from the
`
`dielectric plate than segments of greater radii) [fig 1 & col 2, lines 44-63 and col 3, lines
`
`39-50].
`
`Therefore, the modified structure clearly teaches all of the limitations of the claim.
`
`Specifically, the underlined and bolded segments of the rejection indicate how the
`
`modified structure teaches the limitations of the claim. One of ordinary skill in the art
`
`would place the coil of Ghanbari on the dielectric member of Yoshida'993 modified by
`
`Chen and Yoshida'781 (see fig SB of Yoshida'781) to vary the field configuration within
`
`the chamber to accommodate different size and shape workpieces [Ghanbari - col 2,
`
`lines 44-63].
`
`Furthermore, it is noted that Yoshida'993 modified by Chen and Yoshida'781
`
`teaches various coil configurations may be used with a dielectric member having a
`
`groove [see Yoshida'781 - fig 5A-SC] and the configuration of the coil is not limited in
`
`any way to experience the benefit of the groove (to achieve substantially uniform ion
`
`current density across the diameter of the substrate [Chen — col 5-6, lines 67-8] and
`
`[Yoshida'781 — abstract]). Therefore, one of ordinary skill in the art would further utilize

`
`within the chamber to accommodate different size and shape workpieces [Ghanbari -
`
`col 2, lines 44-63]).
`
`Regarding the argument that the limitation depends upon how deep the groove is
`
`and where the groove is located, it is noted that no particular depth is claimed in the
`
`independent claim. Furthermore, it is noted that the groove is located at the outer
`
`periphery of the coil [see Yoshida’781 — fig 5B]. The outer periphery of the coil of
`
`Ghanbari is located closest to the dielectric window [see Ghanbari — fig 1]. Additionally,
`
`examiner notes that the height of the central part of the coil of Ghanbari is clearly a
`
`result-effective variable and is raised regardless of the shape of the dielectric window
`
`[col 3, lines 51 -65]. It would have been obvious to a person of ordinary skill in the art at
`
`the time of the invention to discover the optimum height of the central part of the coil
`
`through routine experimentation in order to achieve the desired configuration of the
`
`induced field in order to accommodate different size and shape workpieces [Ghanbari ~
`
`col 3, lines 51 -65]. Discovering an optimum value of a result-effective variable involves
`
`only routine skill in the art [MPEP 2144.05].
`
`Simply put, one of ordinary skill in the art would raise the central part of the coil in
`
`Yoshida'993 modified by Chen and Yoshida'781 (i.e. raise the central part of the coil in
`
`fig 5B of Yoshida'781) in order to achieve the desired configuration of the induced field
`
`in order to accommodate different size and shape workpieces [Ghanbari _ col 3, lines
`
`51 -65]. To assert that one would simply utilize the embodiment depicted in fig 5B of
`
`Yoshida'781 ignores the teachings of Ghanbari.

`
`(B) In addition, applicant argues that fig SB of Yoshida’781 shows a distance
`
`between the part of the coil disposed in the groove (the peripheral part of the coil) and
`
`the dielectric member is substantially the same as a distance between a remaining part
`
`of the coil disposed outside of the groove (the central part of the coil) and the dielectric
`
`member. Thus, a person having ordinary skill in the art would have arranged each part
`
`of the coil 40 of Ghanbari to conform to the shape of the dielectric window, as in fig SB
`
`of Yoshida’781.
`
`As set forth above, one of ordinary skill in the art would raise the central part of
`
`the coil in Yoshida'993 modified by Chen and Yoshida'781 (i.e. raise the central part of
`
`the coil in fig SB of Yoshida'781) in order to achieve the desired configuration of the
`
`induced field in order to accommodate different size and shape workpieces [Ghanbari —
`
`col 3, lines 51 -65]. To assert that one would simply utilize the embodiment depicted in
`
`fig SB of Yoshida'781 ignores the teachings of Ghanbari.
`
`Ghanbari is clearly a result-effective variable and is raised regardless of the
`
`shape of the dielectric window [col 3, lines 51-65]. It would have been obvious to a
`
`person of ordinary skill in the art at the time of the invention to discover the optimum
`
`height of the central part of the coil through routine experimentation in order to achieve
`
`the desired configuration of the induced field in order to accommodate different size and
`
`shape workpieces [Ghanbari — col 3, lines 51-65]. Discovering an optimum value of a
`
`result-effective variable involves only routine skill in the art [MPEP 2144.05].
