Abstract:
An integrated circuit structure, comprising:a semiconductor substrate of a material of a first conductivity type wherein said substrate includes at least a first doped portion heavily doped by a material of said first conductivity type;a well region in said substrate, said well region including a first doped portion heavily doped by a material of a second conductivity type, and a second doped portion lightly doped by a material of said second conductivity type;a first metal conductor electrically connected to said first doped portion of said well region for connecting said first doped portion to a first pumped voltage source;a second metal conductor electrically coupled to said second doped portion of said well region for connecting said well region to a second voltage source, the first pumped voltage source being greater in potential than the second voltage source;a third metal conductor electrically coupled to first doped portion of said substrate and connected to a third voltage source; anda Schottky rectifying junction fabricated in said lightly doped portion of said well region, said second voltage source being coupled to said first pumped voltage source through a path including said rectifying Schottky junction.
