  • Patent number: 8748315
    Abstract: The present disclosure relates to a method of forming a back-side illuminated CMOS image sensor (BSI CIS). In some embodiments, the method comprises forming a plurality of photodetectors within a front-side of a semiconductor substrate. An implant is performed on the back-side of the semiconductor substrate to form an implantation region having a doping concentration that is greater in the center than at the edges of the semiconductor substrate. The back-side of the workpiece is then exposed to an etchant, having an etch rate that is inversely proportional to the doping concentration, which thins the semiconductor substrate to a thickness that allows for light to pass through the back-side of the substrate to the plurality of photodetectors. By implanting the substrate prior to etching, the etching rate is made uniform over the back-side of the substrate improving total thickness variation between the photodetectors and the back-side of the substrate.
