Abstract

A method for making a schottky diode structure (10) simultaneously with a polysilicon contact structure (31,33) to a transistor is provided. In a single process step, a polysilicon layer is patterned to expose a single crystal semiconductor region (22a) over one portion of a substrate, while leaving portions the polysilicon layer (31, 33, 29) intact over other portions of the substrate (22b). Multi-layer metal electrodes are deposited and patterned to form a rectifying schottky contact to the exposed single crystal region (22a), and to form an ohmic contact to the exposed polysilicon (31, 33, 29).
