Abstract

A method for adjusting the thickness of a thin semiconductor material layer. The method includes measuring the layer to establish a thickness profile, determining thickness adjustment specifications from the measured thickness profile, and adjusting the thickness of the layer in accordance with the specifications by sacrificial oxidation. An apparatus for adjusting the thickness of a thin layer of semiconductor material according to this method is also disclosed.
