Patent abstract
An imaging cell reduces recombination losses and increases sensitivity by forming a low resistance lateral path with a silicon germanium layer of a conductivity type that is sandwiched between silicon layers of the same conductivity type. The silicon germanium layer also provides a quantum well from which photo-generated electrons find it difficult to escape, thereby providing a barrier that reduces cross-talk.
