Abstract:
1. A Schottky diode comprising: a semiconductor wafer having a body region and a cathode electrode above the body region, wherein said cathode electrode is a bondable metal; an epitaxially formed region on the bottom of the body region; a barrier interface located beneath the epitaxially formed region; an anode contact located beneath the barrier interface, wherein said anode contact is a solderable metal; a package for said semiconductor wafer, said package comprising a conductive heat dissipation surface located beneath said anode, said anode contact is thermally connected and secured to said conductive heat dissipation surface; and a passivation mass is located between the epitaxially formed region and said conductive heat dissipation surface; wherein said solderable metal of said anode contact being a spaced distance from said passivation mass such that adjacent sides of said solderable metal and said passivation mass form a gap that extends to the bottom surface of said solderable metal.
