ABSTRACT:
Deep finger diodes in a body of semiconductor material are fabricated by a thermal gradient zone melting process. A liquid wire or droplet is migrated into the body through one surface to a depth less than the thickness of the body. The migration of the liquid wire or droplet is reversed to remove the wire or droplet from the body leaving a recrystallized material of the body having solid solubility of a material therein.
