Patent ID: 7679042

Claim:
A method for fabricating a pixellated transducer absorbing electromagnetic radiation in a predetermined range of wavelengths, the method comprising the steps of: bonding a wafer of a second predetermined material to a surface of a wafer of a first predetermined material; lapping and polishing to a first predetermined thickness the wafer of said second predetermined material; the lapped and polished wafer of said second predetermined material comprising a layer of said second predetermined material; patterning the layer of said second predetermined material according to a predetermined pattern; refilling the patterned layer of said second predetermined material with a sacrificial material; planarizing an exposed surface of the refilled patterned layer of said second predetermined material; depositing on a surface of a first wafer of a third predetermined material a first polymer layer of a second predetermined thickness; depositing on a surface of a second wafer of said third predetermined material a second polymer layer of a third predetermined thickness; said first polymer layer and said second polymer layer absorbing electromagnetic radiation in a predetermined range of wavelengths; disposing the first polymer layer deposited surface of the first wafer on the second polymer layer deposited surface of the second wafer; adhering the first polymer layer to the second polymer layer; said first wafer, said first polymer layer, said second polymer layer and said second wafer comprising a layered structure; patterning the layered structure with another predetermined pattern; and removing the sacrificial layer.
