DEFINITION

Classification: 257/226

Sensor element and charge transfer device are of different materials or on different substrates (e.g., "hybrid "):

(under subclass 225) Subject matter wherein charge carriers generated in response to the non-electrical input are generated in material which is different than, or is located on a different substrate than, the semiconductor material that contains the charge carrier storage sites.
