Abstract:
A charge pump formed in a silicon-on-insulator (SOI) substrate comprising:a substrate; an insulator formed on said substrate; a semiconductor layer formed on said insulator; a first p-body formed in said semiconductor layer; a second p-body formed in said semiconductor layer; a n+ region formed in said semiconductor layer extending down to said insulator, said n+ region separating said first p-body and said second p-body; and a gate structure formed atop a portion of said first p-body and only a portion of said n+ region, said gate structure over said first p-body and said n+ region forming a switch, said n+ region and said first p-body forming a first diode, said n+ region and said second p-body forming a second diode, said gate structure formed from a thin gate oxide layer underneath a conductive layer.
