Abstract
A two stage threshold adjust implantation process is performed after field oxidation to avoid the effects of dopant redistribution and segregation. At any of several steps in a manufacturing process, only routine implant energy and dose adjustments are required to create a first and a second dopant profile (110, 120) that result in the reduction of edge leakage and threshold voltage sensitivity to device layer thickness of a semiconductor device on a semiconductor on insulator substrate.
