Patent ID: 7358139

Claim:
A method of forming a field effect transistor having a gate comprising a conductive metal or metal compound received over conductively doped semiconductive material, the method comprising: forming transistor gate semiconductive material and conductive material which contacts the semiconductive material thereover into a gate line over a semiconductive material channel region, the gate line comprising semiconductive material sidewalls; oxidizing the semiconductive material sidewalls of the gate line; after the oxidizing, depositing insulative material over the gate line; after the depositing, removing the insulative material effective to expose the transistor gate conductive material but not the transistor gate semiconductive material; and after the removing, forming at least one of a conductive metal or metal compound in electrical connection with the transistor gate semiconductive material to comprise a substantially coextensive elongated portion of a final construction of the gate line of the field effect transistor being formed.
