Title:
IMAGE SENSOR AND DETECTION SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2022/001645
Kind Code:
A1
Abstract:
Provided are an image sensor and a detection system using same, which belong to the field of semiconductor image sensors. The image sensor includes: a first substrate, wherein the first substrate at least includes a photoelectric unit for photoelectric conversion, and N signal transmission channels which are connected to the photoelectric unit, with N being greater than or equal to 1; and a second substrate, which includes N second charge storage units which correspond to the N transmission channels. The transmission channels receive control signals, electrically communicate the photoelectric unit and the second charge storage units, and transfer at least some photo-induced electrons, which are generated in the photoelectric unit, to the second charge storage units. The effect of miniaturization and high integration design of pixels is ensured by means of stacking two substrates; and by means of further providing charge storage units on both of the two substrates, the area of the peripheral region of the pixels can be used, the effect of a higher charge storage amount can be achieved, and the effects such as measurement accuracy can be ensured.
