Abstract
A merged platinum silicide fuse and Schottky diode structure and method of manufacturing the merged structure is presented. The merged structure is formed by an insulating layer having an aperture over a silicon substrate. A shaped layer of polysilicon lies on the insulating layer and contacts the substrate through the aperture; a layer of platinum silicide in the same shape as the polysilicon layer covers the polysilicon layer. The region of polysilicon - PtSi layers over the substrate contact forms a Schottky diode and the region on the insulating layer forms the fuse. This merged structure has superior Schottky diode electrical characteristics and is more compact compared to prior art structures.
