Patent ID: 8658475

Claim:
A method for forming a first stacked body-contacted field effect transistor (FED comprising: providing an insulating layer of a semiconductor die; providing a thin-film semiconductor device layer of the semiconductor die over the insulating layer; forming a body of each of a first plurality of FETs in at least a part of the thin-film semiconductor device layer; forming a polysilicon layer over the thin-film semiconductor device layer; forming a gate of the each of the first plurality of FETs in at least a part of the polysilicon; and forming a lateral isolation band encircling a periphery of the first plurality of FETs, such that the first plurality of FETs is coupled in series and comprises: a first end FET having a first drain, a first gate, a first merged source-drain, and a first body, which is not directly connected to any body of any other of the first plurality of FETs, such that the first merged source-drain is adapted to function as a first source of the first end FET; and a second end FET having a second source, a second gate, and a second body, which is not directly connected to any body of any other of the first plurality of FETs, wherein the lateral isolation band laterally isolates the first plurality of FETs from other devices in the semiconductor die.
