Patent ID: 7791373

Claim:
A semiconductor device comprising a functional circuit comprising a NOR cell comprising: a first input side NOT gate; a second input side NOT gate; a NAND gate having a first input terminal connected to the first input side NOT gate and a second input terminal connected to the second input side NOT gate; and an output side NOT gate having a third input terminal connected to an output terminal of the NAND gate, wherein a first channel width of a first transistor in the first input side NOT gate is smaller than a third channel width of a third transistor in the output side NOT gate, wherein a second channel width of a second transistor in the second input side NOT gate is smaller than the third channel width of the third transistor in the output side NOT gate, wherein the first channel width is 10 μm or less, wherein the second channel width is 10 μm or less, and wherein the third channel width is 5 μm or more.
