Title: Solid-state image pickup device
Inventor: TAKAHASHI HIDEKAZU
IPC: H04N5/374
Filed: 2000-05-22
Abstract: PROBLEM TO BE SOLVED: To enable high speed operation by improving the numerical aperture of a micronized area sensor and reducing the shading of an output signal. SOLUTION: A drain contact 10 and a well contact 11 are made common in the same active region. This constitution can be realized by forming an N+ layer as a drain and a P+ layer for contact with a well to be overlapped pertially. Since potentials of the drain and the well can be taken together in the same region, the number of wirings and contacts is reduced as compared with the conventional structure. Consequently, picture element can be micronized. The numerical aperture can be increased when the size of picture element is identical to the conventional one, so that sensitivity is improved. Since a well contact can be formed in a picture element region, the shading of an output signal can be reduced by restraining fluctuation of a well potential.
