Patent ID: 7271064

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 into a gate line over a semiconductive material channel region, the gate line comprising semiconductive material sidewalls; forming conductive masking material over the transistor gate semiconductive material; 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 and the conductive masking material effective to expose the gate line; 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, the forming the at least one of a conductive metal or metal compound to comprise a substantially coextensive elongated portion of a final construction of the gate line of the field effect transistor being formed comprising deposition of said at least one and patterning and subtractively etching of said at least one.
