A method and apparatus for the formation of oxide in a manner having a planarizing effect on underlying material, e.g., silicon. In particular, an oxide having a nonuniform thickness profile is grown on the underlying material. The nonuniform thickness profile of the oxide is selected according to the nonuniform profile of the underlying material. Subsequent removal of the oxide leaves behind a planarized surface of the underlying material, as compared to the pre-oxidized surface.
