Patent ID: 8354678

Claim:
A diode structure, comprising: a silicon-on-insulator wafer joined to a dielectric layer; an alignment marker formed in the silicon-on-insulator wafer; a back-end-of-line metal wiring and dielectric level formed on the silicon-on-insulator wafer; an alternating n-type and p-type doped region formed on a backside of the silicon-on-insulator wafer, wherein the alternating n-type and p-type doped region includes an n-well cathode region, a first n-well ohmic contact region, a second n-well ohmic contact region, and an anode region; a group of through-silicon vias that extend through the back-end-of-line metal wiring and dielectric level, the silicon-on-insulator wafer, and the dielectric layer; and a group of contacts that connect the group of through-silicon vias to the alternating n-type and p-type doped region.
