Patent ID: 7898052

Claim:
A semiconductor device comprising: a crystalline semiconductor body arranged above a dielectric layer wherein said crystalline semiconductor body comprises a doped connection layer on said dielectric layer, a doped first partial layer on said connection layer and a doped second partial layer on said first partial layer wherein said second partial layer is doped with an opposite conductivity than said connection layer and said first partial layer; a semiconductor junction between said first partial layer and said second partial layer; a photodiode array comprising individual diodes formed by said semiconductor junction with said connection layer forming a common electrode for individual diodes; trenches arranged in said first partial layer and said second partial layer wherein said trenches reach at least as far as said connection layer and divide said photodiode array into individual diodes; a conductive material arranged within said trenches wherein said conductive material is electrically connected to said connection layer; at least one semiconductor circuit comprising CMOS type transistors formed in said semiconductor body and electrically connected to said photodiode array; and metallic contacts forming further electrodes of said individual diodes and forming connections between said semiconductor circuit and said individual diodes.
