ABSTRACT:
An improved semiconductor device that reduces reverse bias junction leakage in a photodiode by using a junction isolation region to isolate the photodiode from a trench isolation region. The improved semiconductor device improves image quality for different applications such as stand-alone digital cameras and digital cameras embedded in other imaging devices such as cellular phones and personal digital assistants.
