Patent ID: 7704786

Claim:
A method of forming an organic inverter comprising: providing a first metal layer having a first portion for coupling a source of a first OFET to a first power supply voltage, a second portion for coupling a drain of the first OFET to an output terminal and to a source of a second OFET, and a third portion for coupling a drain of the second OFET to a second power supply voltage; providing a semiconductor layer for overlapping a portion of the first and second first metal layer portions to form a first OFET active area, and for overlapping a portion of the second and third metal layer portions to a second OFET active area; providing a dielectric layer for overlapping a portion of the first and second first metal layer portions and the semiconductor layer that form the first OFET active area, and for overlapping a portion of the second and third first metal layer portions and the semiconductor layer that form the second OFET active area to isolate the first metal layer and the semiconductor layer from a second metal layer; and providing the second metal layer for overlapping the active area of the first OFET to form a gate of the first OFET and an input terminal, and for overlapping the active area of the second OFET to form a floating gate for the second OFET, wherein the floating gate is not connected to a signal wire.
