Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Election/Restrictions
Applicant's election with traverse of Species A, Subspecies A-1, B-1 B-1-3, C-1, D-1, E-1, F-1, Modifications A-2, B-2, C-2, D-2, E-4, F-2, G-2, H-1, I-2, J1 in the reply filed on 24 March 2026 is acknowledged.
Regarding Applicants arguments regarding Subspecies B: Applicant is correct that the restriction mistakenly says Figs. 4B-C correspond to Subspecies B-2. This should say Figs. 4A-B. However, this does not affect the validity of the restriction. Applicant’s specification says (in paragraph [0138]):
“FIGS. 4 A and 4B illustrate an example in which the insulating layer 107a and the insulating layer 131 illustrated in FIGS. 2B and 2C are changed to an insulating layer 130 and the insulating layer 133, the insulating layer 135, and the insulating layer 137 illustrated in FIGS. 2B and 2C are changed to an insulating layer 134.”
This is the arrangement described in Subspecies B-2 as “where the conductive layers (115a, b) are not covered by insulating layers (107a,b) and the conductive layer (115a) covered directly by insulating layer (131) and the first and second conductive layers are separated by a portion of the insulating layer (134).”
Therefore, the restriction is maintained. However, Examiner notes that applicant’s claims are currently generic to both Subspecies B-1 and B-2, and have the potential for rejoinder should allowed claims be generic to both Subspecies.
Regarding Applicants arguments regarding Subspecies C: Applicant is correct that the properties described are also the openings (121a). Examiner was referring to the top surface of the conductive layer (111a) as shown in Fig. 3A3, 6A3, 7A3, which is in the opening (121a) ([0102] The bottom of the opening portion 121a includes a top surface of the conductive layer 111a.) The shape of the top surface of the conductive layer (111a) appears to conform to the shape of the opening (121a) in the images. Furthermore, Applicant clearly understood the feature to which examiner was referring.
Therefore, the restriction is maintained. However, Examiner notes that applicant’s claims are currently generic to both Subspecies C1-3, and have the potential for rejoinder should allowed claims be generic to both Subspecies.
Regarding Applicants arguments regarding Subspecies D: Examiner concedes that the images relating to Figs. 16A, 19A-30A are not assigned to the correct subspecies. However, the restriction is based on the conductive layer 115 which has clearly different shapes as shown in the B Figs. The restriction clearly articulates the mutually exclusive characteristic is the shape of the conductive layer 115. This is the basis for the restriction, and Applicant has not articulated why the different shapes of the conductive layer 115 are not mutually exclusive. The listing of the Figs. is merely meant to be a tool to aid the Applicant in better understanding what the restriction described is referring to. Any mistake in labelling Figs. does not invalidate the underlying mutually exclusive characteristics described in each of the Subspecies.
Therefore, the restriction is maintained. However, Examiner notes that applicant’s claims are currently generic to both Subspecies D1-6, and have the potential for rejoinder should allowed claims be generic to both Subspecies.
The requirement is still deemed proper and is therefore made FINAL.

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.
Claim(s) 16 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yamazaki as applied to claim 3 above.
Regarding Claim 16, Yamazaki fails to disclose wherein a capacitance of the capacitor (100A) is more than or equal to double a capacitance of a capacitor formed by the seventh conductive layer (145), the fifth insulating layer (151), and the eighth conductive layer (164).
Yamazaki teaches that the capacitance generated between the gate wiring and the source/drain electrode can slow the transistor operation, thus it is desirable to reduce the parasitic capacitance between the gate and the source/drain.
([0150] Large capacitance generated between a gate wiring and the source electrode or the drain electrode might slow the transistor operation and degrade the frequency characteristics of a circuit including the transistor.
[0151] In view of the above, in the transistor of one embodiment of the present invention, parasitic capacitance generated between the third conductive layer and the fourth conductive layer is preferably reduced. In this case, high-speed operation of the transistor can be achieved. A semiconductor device with favorable electrical characteristics can be provided.)
Therefore, it would have been obvious to a person having ordinary skill in the art before the effective filing date of the application to reduce the capacitance between the gate and source/drain in order to achieve a faster switching speed. Therefore, it would be obvious to optimize have the capacitance between the capacitor (100A) be more than or equal to double a capacitance of a capacitor formed by the seventh conductive layer (145), the fifth insulating layer (151), and the eighth conductive layer (164) because it would be obvious to reduce the capacitance between the seventh conductive layer (145), the fifth insulating layer (151), and the eighth conductive layer (164) as much as possible in order to increase the switching speed of the transistor.
Allowable Subject Matter
Claims 4-11 objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims.
The following is a statement of reasons for the indication of allowable subject matter:
Regarding Claim 4, Yamazaki further discloses (as shown in Figs. 32, 40C-D) a memory portion, wherein the memory portion comprises memory cells arranged in a matrix, ([0803] The memory cells 150 are arranged in a matrix three-dimensionally, whereby a memory cell array can be formed.)
wherein each of the memory cells comprises the first transistor, the second transistor, and the capacitor, ([0798] The memory cell 953 includes the transistor M2, the transistor M3, and a capacitor CB.)
However, Yamazaki fails to disclose wherein the sixth conductive layer (120) and the seventh conductive layer (145) are shared by the memory cells arranged in a first direction.
Because the Claim includes limitation that are not found in the prior art, Claim 4 contains allowable subject matter.
Regarding Claims 5-8, Claims 5-8 depend from Claim 4 and contain allowable subject matter for the same reasons.
Regarding Claim 9, Yamazaki fails to disclose wherein the second conductive layer (either 220a or 115 depending on which interpretation above is used) comprises a region extending in a first direction and a region extending in a second direction that is perpendicular to the first direction, and wherein the second conductive layer (220a or 115) comprises a third opening portion in a region where the region extending in the first direction and the region extending in the second direction intersect with each other.
Atanasov also fails to disclose wherein the second conductive layer (108) comprises a region extending in a first direction and a region extending in a second direction that is perpendicular to the first direction, and wherein the second conductive layer (108) comprises a third opening portion in a region where the region extending in the first direction and the region extending in the second direction intersect with each other.
Because the Claim includes limitation that are not found in the prior art, Claim 9 contains allowable subject matter.
Regarding Claim 10, Claim 10 depends from Claim 9 and contain allowable subject matter for the same reasons.
Regarding Claim 11, Yamazaki further discloses (as shown in Figs. 32, 39, 40C-D) a memory portion ([0848] memory array 920), a first driver circuit ([0855] a column driver 924), and a second driver circuit ([0855] a row driver 923),
wherein the memory portion (920) comprises memory cells ([0794] The memory cell 150) arranged in a matrix, ([0848] the memory array 920 includes a plurality of memory cells 950 arranged in a matrix.)
wherein each of the memory cells (950) comprises the first transistor (203E1), the second transistor (200e), and the capacitor (100A), ([0794] The memory cell 150 includes the transistor 200e over the insulating layer 140, the capacitor 100A over the transistor 200e, and the transistor 203E1 over the capacitor 100A.)
wherein a constant potential is supplied to the second conductive layer (165), ([0864] The wiring CAL functions as a wiring for applying a predetermined potential to the second terminal of the capacitor CA)
wherein the first driver circuit is configured to write data to the memory cells and read the data, ([0856] The column driver 924 has a function of writing data to the memory cell 950, reading data from the memory cell 950, and retaining the read data, for example.)
and wherein the second driver circuit is configured to supply a signal to the seventh conductive layer and thereby control reading of the data. ([0856] The row driver 923 has a function of selecting the row specified by the row decoder 941.)
wherein the sixth conductive layer (120) is electrically connected to the first driver circuit (824), ([0765] The other of the source and the drain of the transistor M1 is connected to the wiring BIL)
wherein the seventh conductive layer (145) is electrically connected to the second driver circuit (923), ([0765] The gate of the transistor M1 is connected to the wiring WOL)
However, Yamazaki fails to disclose:
wherein the second conductive layer (165) comprises a region extending in a first direction and a region extending in a second direction that is perpendicular to the first direction,
wherein the second conductive layer (165) comprises a third opening portion in a region where the region extending in the first direction and the region extending in the second direction intersect with each other,
Because the Claim includes limitation that are not found in the prior art, Claim 11 contains allowable subject matter.
