  • Thick extended contact photoconductor
    Patent number: 4482881
    Abstract: A semiconductor photoconductor having low impedance nonmetallic contacts is disclosed which has increased detectivity over prior art photoconductor structures. The improved photoconductor has metallic contacts that are separated by a contact length that is greater than the optical length of the detector. The contact regions of the semiconductor adjacent the detector region are thicker than the detector region. The process for fabricating the photoconductor includes thinning the detector region to an appropriate thickness while preserving the greater thickness of the contact regions.
