Abstract:
A method of fabricating a multiple color infrared detector, comprising the steps of:backside passivating a layer of N-type semiconductor material;backside passivating a layer of P-type semiconductor material;thinning said N-type semiconductor layer to a thickness of about 10 .mu.m;topside passivating said layer of N-type semiconductor material;affixing said layer of P-type semiconductor material to said layer of N-type semiconductor material;thinning said P-type semiconductor layer to a thickness of about 10 .mu.m;forming a first and second electrical contact on said layer of N-type semiconductor material;forming a third electrical contact on said layer of P-type semiconductor material;topside passivating said layer of P-type semiconductor material;passivating a plurality of sidewalls of said layers of N-type and P-type semiconductor material;forming an N-type region in said layer of P-type semiconductor material; andforming a fourth electrical contact in said N-type region.
