ABSTRACT:
A self aligned, lateral-overflow drain antiblooming structure that is insensitive to drain bias voltages and therefore has improved insensitivity to process variations. The length of the antiblooming barrier regions are easily adjusted and determined by photolithography. The self aligned, lateral-overflow drain (LOD) antiblooming structure results in a design that saves space, and hence, improves overall sensor performance. In this structure, an antiblooming potential barrier is provided that is smaller (in volts) than the barriers that separate the pixels from one another so that excess charge will flow preferentially into the LOD as opposed to the adjacent pixels.
