摘要
An image sensor includes a high concentration well region in contact with a device isolation layer extending along a periphery of a photoelectric converting part, which can improve dark current properties of the image sensor. The image sensor also includes a low concentration well region in contact with a sidewall of the device isolation layer overlapped with a transfer gate, which can improve image lag properties of the image sensor. Related fabrication methods are also discussed.
