Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale or otherwise available to the public before the effective filing date of the claimed invention.
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.

Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
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.
Claim 14 is rejected under 35 U.S.C. 103 as being obvious over NAGATO et al (US 20190127848 A1).
Regarding claim 14, Figures 1/5/7 of NAGATO disclose that the method of claim 13, wherein the hydrogen-containing gas contains a hydrogen gas ([0065]) but does not explicitly teach that wherein a mass fraction of the hydrogen gas in the hydrogen-containing gas is 70% or more.
However, it would have been obvious to one having ordinary skill in the art at the time of the invention was made to use the above claimed ranges in order to form an good quality film with lower cost since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or working range involves only routine skill in the art. In re Aller, 105 USPQ 233.
Claim 19 is rejected under 35 U.S.C. 103 as being obvious over HARADA et al (US 20110104896 A1) in view of NAGATO et al (US 20190127848 A1).
Regarding claim 19, Figure 1 of HARADA discloses a non-transitory computer-readable recording medium storing a program that causes, by a computer (the process of HARADA is anticipated to use a non-transitory computer-readable recording medium storing a program that causes a computer to perform the process, please also see [0002] of NAGATO as an evidence wherein an equivalent process is performed using a computer), a substrate processing apparatus to perform a method comprising:
(a) loading a substrate into a process container at a loading temperature (S1-S2, Figure 1, [0109]-[0114]);
(b) setting an interior of the process container to a film formation temperature ([0115]-[0124]);
(c) forming a metal film on a surface of the substrate by supplying a process gas into the process container ([0125]-[0128]); and
(e) unloading the substrate from the process container (S7-S8, Figure 1).
HARADA does not explicitly teach a step (d) setting the interior of the process container to an unloading temperature lower than the loading temperature.
However, NAGATO is a pertinent art which teaches a processing method is provided. The method includes: (a) processing a substrate accommodated in a substrate holding region of a substrate retainer in a process chamber at a first temperature, the substrate retainer including a heat insulating region on one end thereof and the substrate holding region on the other end thereof; (b) supplying a cleaning gas to the heat insulating region at a second temperature variable within a temperature range lower than the first temperature and higher than a room temperature after unloading the substrate accommodated in the substrate retainer; and (c) supplying the cleaning gas to the substrate holding region at a third temperature variable within another temperature range lower than the second temperature after unloading the substrate accommodated in the substrate retainer ([0006]), wherein Figure 7 of NAGATO teaches that the temperature is lower before unloading the substrate.
Thus, it would have been obvious to one of the ordinary skill in the art before the effective filing date of the claimed invention to modify the method of HARADA by using a step of setting the interior of the process container to an unloading temperature lower than the loading temperature according to the teaching of NAGATO in order to form an improved film with improved cleaning of the processing chamber ([0003]-[0004] of NAGATO).
Examiner Notes
A reference to specific paragraphs, columns, pages, or figures in a cited prior art reference is not limited to preferred embodiments or any specific examples. It is well settled that a prior art reference, in its entirety, must be considered for all that it expressly teaches and fairly suggests to one having ordinary skill in the art. Stated differently, a prior art disclosure reading on a limitation of Applicant's claim cannot be ignored on the ground that other embodiments disclosed were instead cited. Therefore, the Examiner's citation to a specific portion of a single prior art reference is not intended to exclusively dictate, but rather, to demonstrate an exemplary disclosure commensurate with the specific limitations being addressed. In re Heck, 699 F.2d 1331, 1332-33,216 USPQ 1038, 1039 (Fed. Cir. 1983) (quoting In re Lemelson, 397 F.2d 1006, 1009, 158 USPQ 275, 277 (CCPA 1968)).
