Abstract :
Planar isolation structures in power devices are produced in 10 min by the migration of patterned liquid alloy zones through silicon wafers in a temperature gradient. Relative to conventional all-diffused and mesa-structured power devices, this unique technique of thermomigration produces a high yield of devices with blocking characteristics closely approaching those predicted by theory.
