Abstract:
1. A method of forming a logic element of an integrated circuit, the logic element including a circuit portion configured or designed opexfonn at least one logic operation, the integrated circuit being fabricated on a substrate, the method comprising: forming a first gate over the substrate, the first gate being comprised La first transistor gate layer; forming a second gate over the substrate, the second gate being comprised of a second transistor gate layer; wherein a portion of the second gate is formed ova a first portion of the first gate, thereby forming a first overlapping gate region; forming a first electrical contact region on the first gate; forming a second electrical contact region on the second gate; wherein the first gate corresponds to a completed first transistor gate and wherein the second gate correspond to a completed second transistor gate of the circuit portion forming a first doped region in the substrate which functions as a source region of the circuit portion; forming a second doped region in the substrate which functions as a region of the circuit portion; forming an active region in the substrate between said source and regions, said active region being designed to enable current flow between said source and drain regions; wherein the first transistor gate includes an active region portion and a contact region portion, the active region portion corresponding to that portion of the first transistor gate which is over the active region: wherein the forming of the completed second transistor gate include removing portions of the second transistor gate layer in a manner which results in formation of the completed second transistor gate such that at least the portion of the completed second transistor gate is formed over the entirety of the active region portion of the first transistor gate; and forming the logic element in a manner which enables the logic element to perform at least one logic operation.
