Title:
LIGHT DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/171914
Kind Code:
A1
Abstract:
The present invention comprises a substrate, and a plurality of pixel parts, wherein the plurality of pixel parts includes a first light detection element of the pixel parts positioned inside an effective region, and a second light detection element of the pixel parts positioned inside a non-effective region. The first light detection element includes a first lower electrode layer, a first lower impurity semiconductor layer, a first intrinsic semiconductor layer, a first upper impurity semiconductor layer, and a first upper electrode layer, and the second light detection element includes a second lower electrode layer, a second lower impurity semiconductor layer, a second intrinsic semiconductor layer, a second upper impurity semiconductor layer, and a second upper electrode layer, wherein the second lower electrode layer is covered by the second lower impurity semiconductor layer and the second intrinsic semiconductor layer.
