Image Sensor with Deep Well Region and Method of Fabrication the Image Sensor.

摘要

An imager, an image sensor included in the imager and a method of fabricating the image sensor are provided. The image sensor having a substrate with front and back sides to produce image data, includes a transparent conductive coating arranged on the back side of the substrate, a first well region of a first conductive type having first and second opposite sides, the first side being arranged adjacent with the front side of the image sensor; and a second well region of a second conductive type, different from the first conductive type and having a deep well region provided adjacent with the second side of the first well region, the transparent conductive coating configured to develop or to receive a first potential and the first well region configured to receive a second potential to substantially deplete a region between the transparent conductive coating and the first well region.
