Abstract
1354802 Schottky diodes RCA CORPORATION 18 Nov 1971 [27 Nov 1970] 53706/71 Heading H1K The Schottky diode shown has a diffused or ion-implanted guard-ring 14 of opposite conductivity type to the body 12 and which when the diode is reverse biased is connected to the surface barrier electrode 20 by an inversion layer. This eliminates problems otherwise caused by the high field at the edges of the electrode. That portion 20b of the electrode under which the inversion layer is needed is preferably made thinner (as shown) than the remainder of the passivation. The passivation may be one or more of silica, alumina, and silicon nitride. Suitable semi-conductors and respective barrier metals are Si/Al, Cr, Rh; Ge/Au, Cr; and A
