The top silicon layer in as-implanted SIMOX wafer is usually too thin to support device fabrication. Hence, an epitaxial layer is usually grown on a SIMOX wafer after oxygen ion implantation and anneal. Because this epitaxial layer is typically very thin,less than 500 nm) and because of the material structure of the S1MOX wafer, special care has to.be exercised in order to obtain desirable epitaxial growth. This paper describes the unique problems of epitaxial growth on SIMOX.
