Claim Rejections – 35 U.S.C. 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.
Claims 1, 3, 4, 6, 8-14 and 22-24 rejected under 35 U.S.C. 103 as being unpatentable over Saito (U.S. Patent Pub. No. 2016/0276425) of record, in view of Leng (U.S. Patent Pub. No. 2019/0392967), in view of Beach (U.S. Patent Pub. No. 2004/0245575) of record for documentary evidence.
Regarding Claim 1
FIG. 5 of Saito discloses an electronic device, comprising: a semiconductor [0074] layer (100); a dielectric [0079] layer (250) above the semiconductor layer, the dielectric layer having a surface extending in a first plane (interface of 260 and 250); a first resistor (right 220) having opposite first (lower) and second (upper) sides, the first side of the first resistor directly on the surface of the dielectric layer, the second side of the first resistor extending in a second plane spaced apart from the first plane, wherein the first resistor includes: a first portion (left), a second portion (middle), and a third portion (right), wherein the first, second, and third portion have a same material; and a second resistor (left 220) having opposite first (lower) and second (upper), the second resistor spaced apart from the first resistor, the first side of the second resistor on the surface of the dielectric layer, the second side of the second resistor extending in the second plane, wherein the first and second resistors include a same material; and a contact (260) connected to the second side of the first portion, wherein the first portion encloses a lateral dimension of the contact.
Saito is silent with respect to “the second portion having a recess with respect to the second plane” and “the recess is entirely filled with an insulating material”.
FIG. 13 of Leng discloses a similar electronic device, comprising a first resistor (122), wherein the first resistor includes: a first portion (124B), a second portion (120), and a third portion (left 124B), wherein the first side of the first resistor directly on the surface of the dielectric layer (102), the second side of the first resistor extending in a second plane spaced apart from the first plane; wherein the first resistor includes a recess extending into the second side of the first resistor, the recess being entirely filled with an insulating material (116) and the first, second, and third portion have a same material.
It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to modify the device of Saito, as taught by Leng. The ordinary artisan would have been motivated to modify Saito in the above manner for purpose of improving integrated resistor performance ([0005] of Leng).
Regarding Claim 3
FIG. 13B of Leng discloses the first and third portions of the first resistor have a first thickness; and the second portion has a second thickness less than the first thickness.
Regarding Claim 4
FIG. 5 of Saito discloses a second dielectric layer (260) above the dielectric layer (250), the first resistor (right 220), and the second resistor (left 220); a first contact (260b) extending in the second dielectric layer and contacting the first portion of the first resistor; a second contact (260d) extending in the second dielectric layer and contacting the third portion of the first resistor, the second contact spaced apart from the first contact along the first direction; a third contact (260b) extending in the second dielectric layer and contacting a portion of the second resistor; and a fourth contact (left 260d) extending in the second dielectric layer and contacting another portion of the second resistor, the fourth contact spaced apart from the third contact, wherein the contact is a first contact.

Regarding Claim 8
With respect to “the second thickness is 50 A or less”, said thickness is related to the desired resistance and the material used for TFR (for example, Para. 34 of Beach states “35 .ANG. for a 1 Kohm silicon chromium resistor”). Therefore, said thickness is considered to be a result effective variable. The claim to a specific thickness therefore constitutes an optimization of ranges. In re Huang, 100 F.3d 135, 40 USPQ2d 1685, 1688 (Fed. Cir. 1996). It would have been obvious to one of ordinary skill in the art at the time of the invention to use the parameters as claimed, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art (MPEP 2144.05).
Regarding Claim 9
Leng discloses the first resistor and the second resistor include silicon-chromium [0022].
Regarding Claim 10
FIG. 5 of Saito discloses a resistor (220), comprising: a patterned film having a first side facing a semiconductor substrate (100) and a second side opposite the first side, the first side extending in a first plane and the second side extending in a second plane spaced apart from the first plane, wherein: the patterned film includes a first portion, a second portion, and a third portion, the second portion extending between the first and third portion; and a first conductive contact (260b) connected to the second side of the first portion; and a second conductive contact (260d) connected to the second side of the third portion, wherein the first, second, and third portion have a same material, the first portion encloses a first lateral dimension of the first conductive contact and the third portion encloses a second lateral dimension of the second conductive contact.
Saito is silent with respect to “the second portion is recessed with respect to the second plane” and “a surface of the second portion is entirely in direct contact with an insulating material, the surface facing the second plane”.

It would have been obvious to one of ordinary skill in the art before the effective filing of the claimed invention to modify the device of Saito, as taught by Leng. The ordinary artisan would have been motivated to modify Saito in the above manner for purpose of improving integrated resistor performance ([0005] of Leng).
Regarding Claim 11

Therefore, said thickness is considered to be a result effective variable. The claim to a specific thickness therefore constitutes an optimization of ranges. In re Huang, 100 F.3d 135, 40 USPQ2d 1685, 1688 (Fed. Cir. 1996). It would have been obvious to one of ordinary skill in the art at the time of the invention to use the parameters as claimed, since it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable ranges involves only routine skill in the art (MPEP 2144.05).
Regarding Claim 13
Saito as modified by Leng discloses a dielectric layer disposed on the patterned film; the first conductive contact extends through the dielectric layer; and the second conductive contact extends through the dielectric layer.
Regarding Claim 14
FIG. 5 of Saito discloses a dielectric layer (260) above the first portion, the second portion, and the third portion; a first conductive contact (260b) extending through the dielectric layer along the third direction and contacting the first portion; a second conductive contact (260d) extending through the dielectric layer along the third direction and contacting the third portion.
