Abstract:
1. A method for making a body contact in a silicon-on-insulator transistor, said method comprising the steps of: placing a shallow trench isolation on a substrate between regions of an SOI layer; depositing a gate conductor over a portion of said substrate; applying a first dummy gate mask over a first portion of said gate conductor; etching said gate conductor such that said gate conductor not comprising said first portion of said gate conductor is removed; depositing an insulator on said substrate; polishing said insulator; applying a second gate mask over a second portion of said gate conductor; etching said gate conductor such that said gate conductor not comprising said second portion of said gate conductor is removed; depositing spacer portions on said substrate such that said spacer portions isolate said second portion of said gate conductor and said insulator from the rest of said transistor; depositing charged implants in said substrate.
