Patent ID: 7955965

Claim:
A method of forming nanophotovoltaic devices, comprising providing a semiconductor-on-insulator wafer having a continuous buried insulating layer separating a thin upper layer from the bulk of the wafer, forming a p-n junction in said upper wafer layer, depositing a first metallic layer on an exposed surface of said thin upper layer so as to form an ohmic contact therewith, removing the bulk portion of the wafer and said continuous insulating layer to generate a structure comprising said upper layer comprising a p-n junction and said metallic layer disposed on a surface thereof, depositing a second metallic layer on an exposed surface of said thin layer opposed to said first metallic layer to form an ohmic contact therewith, applying a photoresist to one of said metallic layers, holographically patterning said resist to generate a two-dimensional holographic recording therein, developing said patterned photoresist to generate a pattern of exposed and unexposed portions, and etching away the exposed portions to generate a plurality of nanophotovoltaic devices.
