SOLID STATE IMAGE PICK-UP DEVICE HAVING A HIGH RESOLUTION AND A HIGH SENSITIVITY

摘要

A solid state image pick-up device having a high resolution and a high sensitivity has a photosensitive section which includes a semiconductor substrate of one conductivity type, a semiconductor layer of the other conductivity type formed on the semiconductor substrate, the semiconductor layer having a plurality of photosensitive element regions and a barrier region which is thinner than the photosensitive element regions, a semiconductor region of the one conductivity type formed on the barrier region, and an insulator film covering the photosensitive regions and the semiconductor region.
