Ibis Technology Corp. develops, manufactures and markets SIMOX-SOI implantation equipment for the worldwide semiconductor industry. SIMOX creates an insulating oxide barrier below the top surface of a silicon wafer through implantation and annealing. The company's proprietary oxygen implanters produce SIMOX-SOI wafers by implanting oxygen atoms just below the surface of a silicon wafer to create a very thin layer of silicon dioxide between the thin operating region of the transistor at the surface and the underlying silicon wafer itself. It was founded in October 1987.
