Title:
PIXEL, SOLID-STATE IMAGE PICKUP DEVICE, AND METHOD OF MANUFACTURING PIXEL
Document Type and Number:
WIPO Patent Application WO/2021/015070
Kind Code:
A1
Abstract:
This pixel 8 comprises: a photoelectric conversion unit 26 that generates a signal voltage according to absorbed light L2 received from a light input surface 26a; and an optical conversion unit 27 that is provided on the light input surface 26a of the photoelectric conversion unit 26 so as to receive incident light L1 and generate the absorbed light L2 to be output to the photoelectric conversion unit 26. The photoelectric conversion unit 26 has a first region 29 having a first impurity concentration, and a second region 31 having a second impurity concentration that is higher than the first impurity concentration. The second region 31 includes the light input surface 26a and is directly in contact with the optical conversion unit 27. The optical conversion unit 27 receives the incident light L1 and generates the absorbed light L2 including evanescent light L2a.
