Patent ID: 7897469

Claim:
A method of manufacturing an Impact Ionization Metal Oxide Silicon device (I-MOS), comprising: providing a semiconductor layer on a buried insulating layer; forming a gate structure including a stack of gate dielectric and polysilicon gate on the semiconductor layer, the gate structure having opposed first and second sides; masking the semiconductor layer on the second side of the gate structure with a first resist; carrying out an implantation to dope a first region on the first side of the stack a first conductivity type; removing the first resist; selectively etching away the gate structure to leave the stack spaced from the doped first region; masking the semiconductor layer on the first side of the gate structure with a second resist; and carrying out an implantation to dope a second region of the semiconductor layer on the second side of the stack and abutted to the stack a second conductivity type opposite to the first conductivity type.
