摘要:A method of fabricating a fin field effect transistor is disclosed. An examplemethod forms a thermal oxide layer as a hard mask for etching a silicon fin on an SOIsubstrate, transcribes a fin pattern, forms a fin FET body by etching using the fin pattern
as an etch mask, and restores a sidewall damaged by the etching remove a sacrificialsilicon oxide layer. The example method also deposits a high-K dielectric as a gatedielectric, deposits a metal layer, planarizes the metal layer to a height of a hard oxide,forms a nitride layer on the planarized metal layer, and patterns the nitride layer using ahard mask for forming a pattern to form a nitride layer pattern. Additionally, the
example method forms a metal gate using the nitride layer pattern, removes a remaininghard oxide mask, and grows a sidewall oxide layer on the metal gate.
