Abstract

A method of fabricating a defect induced buried oxide (DIBOX) region in a semiconductor substrate utilizing a first low energy implantation step to create a stable defect region; a second low energy implantation step to create an amorphous layer adjacent to the stable defect region; oxidation and, optionally, annealing, is provided. Silicon-on-insulator (SOI) materials comprising said semiconductor substrate having said DIBOX is also provided herein.
