Title:

LIGHT DETECTION DEVICE, IMAGING DEVICE AND DISTANT IMAGE ACQUISITION DEVICE

Document Type and Number:

WIPO Patent Application WO/2003/049190

Kind Code:

A1

Abstract:

A photosensitive region includes a semiconductor substrate (40) consisting of a P−type semiconductor and N−type semiconductor regions (41, 42) formed on the front layer of the semiconductor substrate (40), whereby each photosensitive portion includes a semiconductor substrate (40) portion and a set of regions (41, 42) to constitute a photodiode. Regions (41, 42) each have an almost triangular shape when viewed from a light incident direction, with two regions (41, 42) in one pixel formed adjacent to each other at respective one side thereof. A first wiring (44) that electrically connect one region (41) in each pixel in a first direction is provided to extend in the first direction between pixels. A second wiring (47) that electrically connect the other region (42) in each pixel in a second direction is provided to extend in the second direction between pixels.
