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.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
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 2, 4, and 13 are rejected under 35 U.S.C. 103 as being unpatentable over Tada (U.S. PG Pub No US2016/0254276A1), as applied in claims 1, 3, and 12 above, in view of Oh (U.S. PG Pub No US2017/0317155A1).
Regarding claim 2, Tada teaches the thin film transistor (TR) figs. 7-8 [0051] of claim 1. Tada also teaches wherein orthographic projections of the first conductive area (left LDD2, CSC) fig. 8 [0027] and the second conductive area (right LDD2, SCD) fig. 8 [0027] on the substrate (12) fig. 8 [0025] are both L-shaped (have L-shaped perimeters), the first conductive area (left LDD2, CSC) and the second conductive area (right LDD2, SCD) are connected through the channel area (SCC1, LDD1, SCC2) fig. 8 [0028].
However, Tada does not explicitly disclose an orthographic projection of the active layer (SC) fig. 8 [0027-0028] on the substrate (12) is right angle Z-shaped.
Oh teaches a semiconductor device [see fig. 3, 0059] comprising a thin film transistor (D-Tr) fig. 3 [0060] an orthographic projection of the active layer (165) fig. 3 [0060] on the substrate (100) fig. 4 [0064] is right angle Z-shaped [see fig. 3, 0070].
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the shape of the active layer in the thin film transistor of Tada to be z-shaped [0070] in order to enhance its surface area for electrical connections in a limited space [0060] so as to improve the integration density of transistor circuitry [0060, 0070] while maintaining signal quality [0006-0008], as taught by Oh.
Regarding claim 4, Tada teaches the thin film transistor (TR) figs. 7-8 [0051] of claim 3. Tada also teaches wherein orthographic projections of the first conductive area (left LDD2, CSC) fig. 8 [0027] and the second conductive area (right LDD2, SCD) fig. 8 [0027] on the substrate (12) fig. 8 [0025] are both L-shaped (have L-shaped perimeters), the first conductive area (left LDD2, CSC) and the second conductive area (right LDD2, SCD) are connected through the channel area (SCC1, LDD1, SCC2) fig. 8 [0028].
However, Tada does not explicitly disclose an orthographic projection of the active layer (SC) fig. 8 [0027-0028] on the substrate (12) is right angle Z-shaped.
Oh teaches a semiconductor device [see fig. 3, 0059] comprising a thin film transistor (D-Tr) fig. 3 [0060] an orthographic projection of the active layer (165) fig. 3 [0060] on the substrate (100) fig. 4 [0064] is right angle Z-shaped [see fig. 3, 0070].
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the shape of the active layer in the thin film transistor of Tada to be z-shaped [0070] in order to enhance its surface area for electrical connections in a limited space [0060] so as to improve the integration density of transistor circuitry [0060, 0070] while maintaining signal quality [0006-0008], as taught by Oh.
Regarding claim 13, Tada teaches the array substrate (SUB1) fig. 8 [0025] of claim 12. Tada also teaches wherein orthographic projections of the first conductive area (left LDD2, CSC) fig. 8 [0027] and the second conductive area (right LDD2, SCD) fig. 8 [0027] on the substrate (12) fig. 8 [0025] are both L-shaped (have L-shaped perimeters), the first conductive area (left LDD2, CSC) and the second conductive area (right LDD2, SCD) are connected through the channel area (SCC1, LDD1, SCC2) fig. 8 [0028].
However, Tada does not explicitly disclose an orthographic projection of the active layer (SC) fig. 8 [0027-0028] on the substrate (12) is right angle Z-shaped.
Oh teaches a semiconductor device [see fig. 3, 0059] comprising a thin film transistor (D-Tr) fig. 3 [0060] an orthographic projection of the active layer (165) fig. 3 [0060] on the substrate (100) fig. 4 [0064] is right angle Z-shaped [see fig. 3, 0070].
Therefore, it would have been obvious to someone of ordinary skill in the art before the effective filing date of the claimed invention to have modified the shape of the active layer in the thin film transistor of Tada to be z-shaped [0070] in order to enhance its surface area for electrical connections in a limited space [0060] so as to improve the integration density of transistor circuitry [0060, 0070] while maintaining signal quality [0006-0008], as taught by Oh.
