Abstract:
1. A method of making a Schottky barrier diode (SBD), utilizing an anode contact and a cathode contact, and that the cathode contact may be shared with an NFET source/drain, the cathode body series resistance being with a substrate bulk; the method comprising the sequential steps of: (a) applying a N-type light implant to prepare a surface donor impurity concentration in all of the NFET and SBD contact areas to the level around 1.0-5.0 E16 atoms/cm (b) blocking out the anode area by a photo-resist; (c) implanting with N++ donor impurity concentration to the level of about 1.0E 20 atom/cm (d) providing a low barrier metal deposition to provide the SBD.
