Image sensing device

Abstract

An image sensing device includes a plurality of unit pixels, each of which includes a plurality of sub-pixels. Each of the unit pixels is structured to respond to incident light to produce photocharges indicative of detected incident light and includes sub-pixels. Each sub-pixel includes a control region configured to generate, within a substrate in which the sub-pixels are disposed, a current that carries the photocharges, a detection region spaced from the control region and configured to capture the photocharges carried by the current, a plurality of first isolation portions disposed between two adjacent sub-pixels, a second isolation portion disposed to surround the sub-pixels, and a voltage applying region disposed at a center portion of the unit pixel and configured to receive a first voltage.

Dependencies are inferred from the claim text.
