Claim Rejections - 35 USC § 103
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, 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.
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.
Claim(s) 2-3 and 6-7 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lai et al., US 2009/0294065.
With respect to the claimed distance between a top surface of the substrate support and a bottom surface of the window (claims 2-3), Lai et al. discloses that the distance between the bottom surface of the window and a top surface of the substrate support is in a range of 1/20 and 1/5 of the distance between the top surface of the substrate and the bottom surface of the ceiling of the chamber in order to ensure that the coil is effectively immersed in the plasma (see, for example, paragraph 0018). Therefore, a prima facie case of obviousness still exists because it would have been obvious to one of ordinary skill in the art before the filing date of the instant claimed invention to optimize the distance between a top surface of the substrate support and a bottom surface of the window during routine experimentation depending upon, for example, the desired coil immersion in the chamber and the desired plasma characteristics, and such limitation would not lend patentability to the instant application absent the showing of unexpected results.
Regarding the claimed outer diameter of the inductive coils (claims 6-7), Lai et al. discloses that the inductive coils have a cylindrical diameter that is a fraction of the workpiece diameter and/or a fraction of the diameter of the gas distribution plate (see, for example, paragraph 0013 and claims 2 and 12). Therefore, a prima facie case of obviousness still exists because it would have been obvious to one of ordinary skill in the art before the filing date of the instant claimed invention to optimize the outer diameter of the inductive coils during routine experimentation depending upon, for example, the desired plasma characteristics, and such limitation would not lend patentability to the instant application absent the showing of unexpected results.
Claim(s) 8-9 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lai et al., US 2009/0294065 in view of Park et al., US 2012/0061022.

Claim(s) 26-28 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lai et al., US 2009/0294065 in view of Park et al., US 2012/0061022, as applied to claims 8-9 above, and further in view of Collins, US 6,361,644 or Lo et al., US 2014/0273537 and Tomioka et al., US 5,897,713 and Koshimizu, US 2010/0243162.

Therefore, in view of these disclosures, it would have been obvious to one having ordinary skill in the art before the effective filing date of the claimed inventio to modify the apparatus of Lai et al. modified by Park et al. as to comprise the inductive coils embedded within the window because such configuration is known and used in the art as a suitable configuration to effectively and efficiently hold, support and protect the inductive coil.
With respect to the F inductive coils being an integer greater than three, it should be noted that Park et al. discloses an embodiment wherein the two coils 708 and 709, which read on the F coils, surround a coil 707, which read on the E coils (see, for example, Fig. 7d). Therefore, in the apparatus of Lai et al. modified by Park et al. the F inductive coils would be more than three. Also, Tomioka et al. discloses a substrate processing apparatus comprising more than three inductive coils (see, for example, Fig. 14). Therefore, in view of this disclosure, it would have been obvious to one having ordinary skill in the art before the filing date of the claimed invention to modify the apparatus of Lai et al. modified by Park et al., as to comprise more than three inductive coils because such configuration is known and used in the art as a suitable configuration to effectively and efficiently generate uniform inductive plasma, control ion density and/or achieve uniformity of the plasma ion density within the chamber. Additionally, a prima facie case of obviousness still exists because it would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to optimize the number of F inductive coils during routine experimentation depending upon, for example, the desired plasma characteristics and/or plasma density, and such limitation would not lend patentability to the instant application absent the showing of unexpected results.
With respect to the E inductive coils delivering RF energy to the F inductive coil, it should be noted that Collins discloses embodiments in which coils 800,810/820,830/840a,840b,840c are connected to each other (see, for example, Figs. 32-34 shown below and their descriptions).

With respect to claims 27-28, it should be noted that in the apparatus of Lai et al. modified by Park et al., the E inductive coils (coil 701, 703, 705 and 707) of the first array are larger than the F inductive coils (702, 704, 706, 708-709) of the third array (see, for example, Figs. 7a-d of Park et al.). Additionally, in the embodiment of Fig. 7d, F would be greater (in number/quantity) than E since the embodiment shows two F coils (708-709) for one E coil (707). Furthermore, it should be noted that the teachings could also be interpreted as the inductive coils 701, 703, 705 and 707 reading on the F inductive coils while the coils 702, 704, 706, 708-709 could read on the E inductive coils, and thereby the F coils would be greater (in size) than the E coils (see, for example, Figs. 7a-d of Park et al.).
Claim(s) 29 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lai et al., US 2009/0294065 in view of Park et al., US 2012/0061022 and Collins, US 6,361,644 or Lo et al., US 2014/0273537 and Tomioka et al., US 5,897,713 and Koshimizu, US 2010/0243162, as applied to claims 26-28 above, and further in view of Weldon et al., US 6,108,189 or Takayuki et al., JP 2010-010417 and Shannon et al., US 2009/0298287.

Therefore, in view of this disclosure, it would have been obvious to one having ordinary skill in the art before the filing date of the claimed invention to modify the apparatus of Lai et al. modified by Park et al. and Collins or Lo et al. and Tomioka et al. and Koshimizu and Weldon et al. or Takayuki et al., so as to comprise the claimed number of RF drive circuits because such structure is known and used in the art as a suitable configuration to effectively and efficiently control the supply of a desired power to the electrodes, thereby optimizing the apparatus and the method performed within the apparatus.
Claim(s) 30 is/are rejected under 35 U.S.C. 103 as being unpatentable over Lai et al., US 2009/0294065 in view of Weldon et al., US 6,108,189 or Takayuki et al., JP 2010-010417 and Shannon et al., US 2009/0298287.
Lai et al. is applied as above but does not expressly disclose the claimed G electrode array. Weldon et al. discloses a substrate processing system comprising an array of G electrodes 110 embedded in the substrate support, wherein G is an integer greater than three; and RF circuit 120 to output RF power to the electrodes; (see, for example, Figs. 2 and 13d, and their descriptions, Figs. 2 and 13d are shown below).

Therefore, in view of these disclosures, it would have been obvious to one having ordinary skill in the art before the filing date of the claimed invention to modify the apparatus of Lai et al. so as to comprise the claimed electrodes embedded in the substrate because such structure is known and used in the art as a suitable configuration to effectively and efficiently control and/or change the thickness of the ion sheath of the plasma above the substrate and thereby optimize the apparatus and the method performed within the apparatus.
With respect to the claimed fourth array of RF direct drive circuits to output power to the electrodes being greater than three, Shannon et al. discloses a substrate processing system comprising electrodes embedded in the substrate support and more than three RF drive circuits 170d/170e/170f/180/185 to output RF power to the electrodes (see, for example, Figs. 12A and 12B and their descriptions, Fig. 12 A is shown below).
