Abstract
Dielectrically isolated regions of single crystal silicon are produced through the use of a specific melting process. In this process, a substrate having regions of single crystal silicon contacting regions of non-single crystal silicon that overlie a dielectric material are treated. In particular, the entire region(s) of non-single crystal silicon is melted utilizing primarily radiant energy. Cooling is then initiated and the molten silicon is converted into a region of single crystal material. Isolation is completed by removing the appropriate regions of single crystal silicon.
