Bohr teaches a semiconductor device(Fig. 4) wherein the first silicon nitride insulating layer(300, ¶0031) makes contact with the first sidewall insulating film(right 108, ¶0032) and the second sidewall insulating film(left 108, ¶0032) in the second direction. It would have been obvious to one of ordinary skill in the art at the time of invention to modify the device of Orlowski, so that the first silicon nitride insulating layer makes contact with the first sidewall insulating film and the second sidewall insulating film in the second direction, as taught by Bohr, in order to electrically isolate the gate electrode and prevent a short between the gate electrode and contacts(¶0051).
Claims 29-30 are rejected under pre-AIA 35 U.S.C. 103(a) as being unpatentable over Orlowski (US 2007/0254435 A1) and Bohr et al. (US 2011/0156107 A1) as applied to claim 28, further in view of Zhu et al. (US 2006/0160317 A1) as cited in the IDS of 8/3/2022, all of record.
Regarding claim 29, Orlowski, in view of Bohr, teaches the semiconductor device according to claim 28, but is not relied on to teach the first silicon nitride insulating layer is a first stress application layer, and the second silicon nitride insulating layer is a second stress application layer.
Zhu teaches a semiconductor device(Fig. 8) including a field effect transistor wherein the first silicon nitride insulating layer(28, ¶0019, ¶0027) is a first stress application layer(¶0027), and the second silicon nitride insulating layer(22, ¶0019, ¶0027) is a second stress application layer(¶0027). It would have been obvious to one of ordinary skill in the art at the time of invention to modify the device of Orlowski, so that the first silicon nitride insulating layer is a first stress application layer, and the second silicon nitride insulating layer is a second stress application layer, as taught by Zhu, in order to enhance the stress in the channel forming region(¶0027).
Regarding claim 30, Orlowski, in view of Bohr, teaches the semiconductor device according to claim 29, but is not relied on to teach the first stress application layer applies a first stress to the channel forming region(16, ¶0025) and the second stress application layer applies a second stress to the channel forming region(16, ¶0025), and a direction of the first stress is different from a direction of the second stress.
Zhu teaches a semiconductor device(Fig. 8) including a field effect transistor wherein the first stress application layer(28, ¶0027) applies a first stress to the channel forming region(not labeled, ¶0027), and the second stress application layer(22, ¶0027) applies a second stress to the channel forming region(not labeled, ¶0027), and a direction of the first stress is different from a direction of the second stress(¶0027). It would have been obvious to one of ordinary skill in the art at the time of invention to modify the device of Orlowski, so that the first stress application layer applies a first stress to the channel forming region and the second stress application layer applies a second stress to the channel forming region, and a direction of the first stress is different from a direction of the second stress, as taught by Zhu, in order to enhance the stress in the channel forming region(¶0027).
Response to Arguments
Applicant’s arguments with respect to claim 25-60 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
