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. Claim 6 is rejected under 35 U.S.C. 103 as being unpatentable over Lin as applied to the claims above. Claim 6 Lin teaches the integrated circuit of claim 1, comprising: a first subfin region (illustrated fig. 18, see annotation below ) under the semiconductor fin; a first dielectric layer (210 in region 204 fig. 18) adjacent to the first subfin region; a second subfin region (see annotation below) under the plurality of semiconductor bodies; and a second dielectric layer (210 in region 202 fig. 18) adjacent to at least a portion of the second subfin region. Lin does not teach the second dielectric layer having a greater thickness than the first dielectric layer. It would have been obvious to one of ordinary skill in the art before the effect filing date of the claimed invention to change the relative size of the second dielectric layer Lin teaches such that “the second dielectric layer having a greater thickness than the first dielectric layer” to increase the effective insulation between second semiconductor device and adjacent device and/or to prevent shorting and/or decrease parasitic capacitance and/or changes in relative size and/or proportion is prima facie type obviousness [See MPEP 2144.04 IV. A] PNG media_image2.png 633 824 media_image2.png Greyscale Annotated fig. 18: highlighting the subfin regions of claim 6 Claims 9-14 are rejected under 35 U.S.C. 103 as being unpatentable over Lin as applied to the claims above, and further in view of US 10553495 B2 Cheng et al hereafter “Cheng”. Claim 9 Lin teaches an electronic device, comprising: a substrate (208 fig. 18 and fig. 3); a first semiconductor device (206c fig. 18 and fig. 3) on the substrate and having a semiconductor fin (212c fig. 18, fig. 3 and fig. 5B) extending in a first direction (Y fig. fig. 18, fig. 3 and fig. 5B) between a first source region (sufficiently illustrated fig. 5B 240 -Y) and a first drain region ( sufficiently illustrated fig. 5B 240 +Y), and a first gate structure (comprising 272 in region 204 and 250c fig. 18) extending in a second direction (X fig. 18) over the semiconductor fin, the first gate structure having a first gate dielectric structure (250c fig. 18) and a first gate electrode (272 in region 204 fig. 18) on the first gate dielectric structure; and a second semiconductor device (206a and/or 206b fig. 18, fig. 3 and fig. 5A) on the substrate and having a plurality of semiconductor nanoribbons (220 fig. 18, fig. 3 and fig. 5A) extending in the first direction between a second source region (sufficiently disclosed 240 -Y fig. 5A) and a second drain region (sufficiently disclosed 240 +Y fig. 5A), and a second gate structure (272 in region 202 and 250a and/or 250b fig. 18) extending in the second direction over the plurality of semiconductor nanoribbons, the second gate structure having a second gate dielectric structure (250a and/or 250b fig. 18) and a second gate electrode (272 in region 202 fig. 18) on the second gate dielectric structure; wherein the first gate dielectric structure includes a first gate oxide layer (230 fig. 18, Paragraph 0024, “the interfacial layer 230 may include a dielectric material such as an oxide layer”) and the second gate dielectric structure includes a second gate oxide layer (252a and/or 252b fig. 18, Paragraph 0033 “The interfacial layers 252a and 252b may include a dielectric material such as an oxide layer”), wherein the first gate oxide layer is at least 2 nm thicker than the second gate oxide layer [paragraph 0033 discloses with sufficient specificity wherein the second gate oxide layer 252a and/or 252b have a range of thickness between 12 Å to 14 Å, while the first gate oxide layer has a thickness between 20 Å to about 50 Å, See MPEP 2131.03 II. ]. Lin does not explicitly teach a chip package comprising one or more dies, at least one of the one or more dies comprising the electronic device as shown above. Cheng teaches a multichip package comprising a plurality of chips in bare die and/or packaged form comprising an integrated circuit chip [sufficiently disclosed Column 9 lines 18-35]. It would have been obvious to one of ordinary skill in the art to substitute integrated circuit and/or the chip and/or die of Cheng with the Integrated circuit and/or chip and/or die as taught by Lin and that “a chip package comprising one or more dies, at least one of the one or more dies” comprising the electronic device as shown above substituting equivalents known for the same purpose is prima facie type obviousness [See MPEP 2144.06] in this case the purpose being a logic circuit and/or integrated circuit. Claim 10 Lin in view of Cheng teaches as shown above the electronic device of claim 9, wherein the first gate dielectric structure includes a first layer of high-k material (254c fig. 18, Paragraph 0032 “high-k”) and the second gate dielectric structure includes a second layer of high-k material.
