Abstract
Disclosed is a rectifier pellet and a method for the fabrication thereof. A layer of oxide is grown on a semiconductor wafer that has been diffused to form a plurality of rectifier pellets, and openings are etched in the oxide at locations corresponding to each pellet. Gold is diffused through the openings into a preselected distribution to reduce turnoff time. Grooves are etched to facilitate glass passivation and division of the wafer into pellets.
