Patent ID: 8610183

Claim:
An integrated circuit, comprising: a monolithic p-type semiconductor substrate; and a first field controlled diode, including: a p-type channel region located in said substrate; an n-type lower depletion gate located in said substrate under said channel region; an n-type lower gate link located in said substrate and contacting a top surface of said bottom depletion gate; an upper gate located in said substrate over said channel region; a p-type anode well located in said substrate abutting said channel region and contacting said top surface of said bottom depletion gate; a p-type anode located in said anode well; a p-type cathode well located in said substrate abutting said channel region opposite from said anode well and contacting said lower depletion gate; an n-type cathode located in said cathode well; and a surface control element at a top surface of said substrate in said channel region between said top gate and said cathode.
