Patent ID: 6885077

Claim:
A Schottky diode, comprising: a semiconductor body having a top side; a weakly-conductive doped well formed in said semiconductor body; a metallic layer on said well for forming a Schottky junction with lateral edges delimiting said Schottky junction, said lateral edges being at least one of curved, ramified, and rimose; said metallic layer being at least one layer selected from the group of thin layers consisting of: a liner of a contact hole filling extending in a dielectric layer covering said top side, a metal silicide layer, and a liner on said metal silicide layer; and a contact region being highly doped for a low-impedance contact connection and having a lateral boundary in said doped well, said lateral boundary having one of a lattice-shaped structure, a finger-shaped structure, a comb-shaped structure, an irregularly curved edge, a ramified edge, and a rimose edge.
