Abstract
Disclosed is a Schottky diode having a platinum silicide Schottky anode layer (25) formed in electrical contact with an underlying silicon semiconductor layer (14). A sidewall oxide (36) is formed around the periphery of the platinum silicide area (25) to prevent etching processes from exposing a portion of the underlying silicon semiconductor layer (14). A titanium tungsten diffusion barrier layer (26) and an aluminum composition layer (28) are formed thereover to provide electrical contact to the Schottky diode.
