Regarding claim 17 , Chen teaches all of the features of claim 16. Chen further teaches wherein b) includes generating a hydrogen radical from the hydrogen-containing gas and supplying the hydrogen radical to the substrate (see [0032]). Regarding claim 18 , Chen teaches all of the features of claim 17. Chen further teaches wherein the hydrogen-containing gas includes at least one of a H 2 gas, a D 2 gas, a H 2 0 gas, a NH 3 gas, a silicon hydride gas, a PH 3 gas, a B 2 H 6 gas, or a hydrocarbon gas (see [0032]). Regarding claim 19 , Chen teaches all of the features of claim 12. Chen further teaches wherein a fourth step of performing a), a fifth step of performing b) after the fourth step, and a sixth step of performing c) after the fifth step are repeated a plurality of times (see [0034]) in view of [0031-0033]). Regarding claim 22 , Chen teaches all of the features of claim 12. Chen further teaches wherein the metal-containing catalyst includes a metal, semimetal or compound thereof having a Lewis acid property ( 204 ; [0031]).

Regarding claim 24 , Chen teaches all of the features of claim 12. Chen further teaches wherein b) includes generating a hydrogen radical from the hydrogen-containing gas and supplying the hydrogen radical to the substrate (see [0032]). Regarding claim 25 , Chen teaches all of the features of claim 24. Chen further teaches wherein the hydrogen-containing gas includes at least one of a H 2 gas, a D 2 gas, a H 2 0 gas, a NH 3 gas, a silicon hydride gas, a PH 3 gas, a B 2 H 6 gas, or a hydrocarbon gas (see [0032]) . Claim Rejections - 35 USC § 103 07-20-aia AIA 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. Notes : when present, semicolon separated fields within the parenthesis (; ;) represent, for example, as ( 30A ; Fig 2B; [0128]) = (element 30A ; Figure No. 2B; Paragraph No. [0128]). For brevity, the texts “Element”, “Figure No.” and “Paragraph No.” shall be excluded, though; additional clarification notes may be added within each field. The number of fields may be fewer or more than three indicated above. These conventions are used throughout this document. 07-21-aia AIA 3. Claim s 20-21 are rejected under 35 U.S.C.103 as being unpatentable over Chen et al. (US 20160233084 A1; hereinafter Chen ), in view of the following statement . Regarding claim 20 , Chen teaches all of the features of claim 12. Chen further teaches wherein a seventh step of performing a), and (see below for “ a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ”). As noted above, Chen does not expressly disclose “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times” . However, the Applicant has not presented persuasive evidence that the claimed “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ” is for a particular purpose that is critical to the overall claimed invention (i.e. the invention would not work without wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ). Also, the Applicant has not shown that “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ” produces a result that was new or unexpected enough to patentably distinguish the claimed invention over the cited prior art. Instead, Claim 21 of the instant disclosure discloses other possible options such as “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times”, and Claim 19 of the instant disclosure discloses other possible options such as “wherein a fourth step of performing a), a fifth step of performing b) after the fourth step, and a sixth step of performing c) after the fifth step are repeated a plurality of times”. Therefore, no rationale is given that the invention will not function without “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ”. Thus, the claimed “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ” is not critical to the invention. In view of the above, as there is no persuasive evidence that the particular configuration of “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ” is significant. Thus, the claimed limitation of “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ” is a matter of choice which a person of ordinary skill in the art would have found obvious. Therefore, the claimed limitation of “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times ” is not patentable over Chen . Regarding claim 21 , Chen teaches all of the features of claim 12. Chen further teaches wherein a nineth step of alternately repeating a) and (see below for “ b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ”). As noted above, Chen does not expressly disclose “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times” . However, the Applicant has not presented persuasive evidence that the claimed “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ” is for a particular purpose that is critical to the overall claimed invention (i.e. the invention would not work without wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ). Also, the Applicant has not shown that “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ” produces a result that was new or unexpected enough to patentably distinguish the claimed invention over the cited prior art. Instead, Claim 20 of the instant disclosure discloses other possible options such as “wherein a seventh step of performing a), and a eighth step of alternately repeating b) and c) after the seventh step are repeated a plurality of times”, and Claim 19 of the instant disclosure discloses other possible options such as “wherein a fourth step of performing a), a fifth step of performing b) after the fourth step, and a sixth step of performing c) after the fifth step are repeated a plurality of times”. Therefore, no rationale is given that the invention will not function without “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ”. Thus, the claimed “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ” is not critical to the invention. In view of the above, as there is no persuasive evidence that the particular configuration of “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ” is significant. Thus, the claimed limitation of “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ” is a matter of choice which a person of ordinary skill in the art would have found obvious. Therefore, the claimed limitation of “wherein a nineth step of alternately repeating a) and b) and a tenth step of performing c) after the nineth step are repeated a plurality of times ” is not patentable over modified Chen.
