Patent 7714369 was granted and assigned to Texas Instruments on May, 2010 by the United States Patent and Trademark Office.
A semiconductor chip that has a photodiode formed on it, a semiconductor device including the semiconductor chip, and manufacturing methods thereof. A second semiconductor region 11 is formed in light-receiving region R of first semiconductor region 10. First bumps 12 are formed outside light-receiving region R. Second bump 13 is formed in a ring-shape around light-receiving region R between region R and first bumps 12. Semiconductor chip T is assembled on assembly substrate S, and resin layer 30 is formed between chip T and substrate S in the region outside of said light-receiving region R.
