Abstract

A method for forming a silicon on insulator substrate includes the step of dissociating a plasma of molecules including at least any one of oxygen and nitrogen to obtain ions. The ions are accelerated by passage through gaps between acceleration electrodes at a predetermined acceleration energy for irradiation of the accelerated ions onto a silicon substrate which is heated to form an insulation film within the silicon substrate.
