Abstract

Dielectrically isolated single crystal silicon of high quality is produced by an extremely convenient process. This process involves the fusing of two silicon bodies where at least one of these bodies has a region of silicon oxide. The bodies are contacted so that the silicon oxide is at an interface between the two bodies. The bodies are then heated to an elevated temperature while applying a nominal electrical potential across the interface. This combination of applied potential and temperature permanently fuses the two bodies without producing any significant damage to the crystal quality of these bodies.
