Title:
CHARGE MODULATION ELEMENT AND SOLID-STATE IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/118884
Kind Code:
A1
Abstract:
Provided are: a charge modulation element which makes it easy to keep an electric field constant across a long charge-transfer-path distance, and makes it possible to avoid problems caused by interface defects or the like; and a solid-state imaging device. The charge modulation element is equipped with: a first charge-storage region (61), a second charge-storage region (62), a third charge-storage region (63), and a fourth charge-storage region (64) which are provided in symmetrical positions relative to the center position of a light-receiving region; and a first electric-field-control electrode pair (41a, 41b), a second electric-field-control electrode pair (42a, 42b), a third electric-field-control electrode pair (43a, 43b), and a fourth electric-field-control electrode pair (44a, 44b) which change the depletion potential of the charge transfer path, and are positioned on both sides of the charge transfer path leading from the center position of the light-receiving region to each of the first charge-storage region (61), the second charge-storage region (62), the third charge-storage region (63), and the fourth charge-storage region (64).
