Abstract
A photosensitive sensor includes a pixel formed by a photosensitive region in a first semiconductor material, a read region in a second semiconductor material, and a transfer gate facing the parts of the first semiconductor material and the second semiconductor material located between the photosensitive region and the read region. The first semiconductor material and the second semiconductor material have different band gaps and are in contact with one another to form a heterojunction facing the transfer gate.
