Abstract
An improved method for fabricating polysilicon Schottky clamped transistors and vertical fuse devices in the same semiconductor structure is disclosed. The resulting structure yields an improved Schottky clamped transistor and vertical fuse device. The improved Schottky transistor has a silicide rectifying contact between the base and collector of the transistor, the vertical fuse is provided with a direct contact between an aluminum contact metal and a polysilicon emitter contact.
