摘要： A method of forming a fin field effect transistor on a semiconductor substrate includes forming a fin-shaped active region vertically protruding from the substrate. An oxide layer is formed on a top surface and opposing sidewalls of the fin-shaped active region. An oxidation barrier layer is formed on the opposing sidewalls of the fin-shaped active region and is planarized to a height no greater than about a height of the oxide layer to form a fin structure. The fin structure is oxidized to form a capping oxide layer on the top surface of the fin-shaped active region and to form at least one curved sidewall portion proximate the top surface of the fin-shaped active region. The oxidation barrier layer has a height sufficient to reduce oxidation on the sidewalls of the fin-shaped active region about halfway between the top surface and a base of the fin-shaped active region. Related devices are also discussed.
