Abstract
A method of preparing a single crystal semiconductor handle wafer in the manufacture of a semiconductor-on-insulator device is provided. The single crystal semiconductor handle wafer is prepared to comprise a charge trapping layer, which is oxidized. The buried oxide layer in the resulting semiconductor-on-insulator device comprises an oxidized portion of the charge trapping layer and an oxidized portion of the single crystal semiconductor device layer.
