图像传感器在光电转换装置下具有反射金属线

Image sensor having reflective metal lines under photoelectric conversion devices
Abstract:
An image sensor includes at least one photoelectric conversion device formed in a silicon substrate, at least one lens formed on one side of the photoelectric conversion device and configured to collect light, a dielectric layer formed on the other side of the photoelectric conversion device and a reflective pattern formed on the dielectric layer. The reflective pattern serves as an electrical circuit interconnection and is configured to reflect the light passing through the dielectric layer such that the light is absorbed to the silicon substrate again.
