Abstract:
1. 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; 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 gate line; 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; and the field effect transistor gate comprising a floating gate field effect transistor gate, the method comprising forming the gate line to comprise a plurality of floating gates underlying a control gate line, the oxidizing also oxidizing sidewalls of the floating gates.
