Low cost reduced blooming device and method for making the same

An image sensing device including a wafer of a single crystal semiconductor having a first surface with an input signal sensing region extending into said wafer from said first surface, an enhanced conductivity layer extending about 300 A into said wafer from said first surface for preventing recombination of minority carriers at said first surface, means within said input signal sensing region for controlling blooming within said sensing region, and a second surface with a plurality of charged storage regions extending into said wafer from said second surface, the improvement wherein said means for controlling blooming comprises a plurality of recombination centers forming a recombination layer extending along approximately 100% of said first surface and spaced about 0.9 to 1.1 microns therefrom.
