Patent ID: 7071043

Claim:
A method of forming a field effect transistor comprising: providing masking material over semiconductive material of a semiconductor substrate, the masking material masking at least a portion of a transistor channel area; while the masking material masks at least a portion of the transistor channel area, forming a lightly doped drain region within a source/drain area of semiconductive material of the semiconductor substrate; after forming the lightly doped drain region, etching an opening into the source/drain area of the semiconductor substrate, the opening having a base comprising semiconductive material; after the etching, forming insulative material within the opening over the semiconductive material base, the insulative material less than completely filling the opening and having a substantially uniform thickness across the opening; forming semiconductive source/drain material within the opening over the insulative material within the opening; and after forming the lightly doped drain region, providing a transistor gate operatively proximate the semiconductive source/drain material.
