Patent ID: 7015562

Claim:
A high-voltage diode, comprising: an anodal p-conducting zone being doped with a dose of 1.3–6×10 12 dopant atoms cm −2 ; a cathodal n − -conducting drift zone forming a pn junction with said anodal p-conducting zone; a p + -conducting anode emitter disposed in said anodal p-conducting zone, said anodal p-conducting zone being lighter doped than said p + -conducting anode emitter, said p+-conducting anode emitter having a relatively high surface concentration doping with only a small penetration depth, said p + -conducting anode emitter having a dopant dose lying between 5×10 12 dopant atoms cm −2 and 2×10 13 dopant atoms cm −2 ; an anode metallization layer adjoining said p+-conducting anode emitter; a cathode metallization layer; an n + -conducting cathode emitter adjoining said cathode metallization layer; and an n-conducting zone disposed between said cathodal n − -conducting drift zone and said n + -conducting cathode emitter.
