Patent ID: 8557647

Claim:
A method for forming a field effect transistor device, the method including: forming at least one layer of a feature material on a substrate, wherein the feature material comprises a gate dielectric layer; patterning a photolithographic resist material on only a first portion of the at least one layer of the feature material; removing one or more second portions of the feature material following the patterning of the photolithographic resist material to define a feature and one or more exposed regions of the substrate, wherein the one or more exposed regions are not located between the photolithographic resist material and the first portion of the at least one layer of the feature material; depositing a masking material layer over the photolithographic resist material and the one or more exposed regions of the substrate; modifying the one or more exposed portions of the substrate by passing ions through the masking material layer and depositing the ions in the one or more exposed portions of the substrate; and removing the masking material layer and the photolithographic resist material following the modifying.
