DEFINITION

Classification: 438/78

Having structure to improve output signal (e.g., exposure control structure, etc.):

(under subclass 75) Process for making a charge transfer device which contains structural means to improve the electrical signal it generates in response to the electromagnetic radiation.

(1) Note. The structural means to improve the output signal may serve to control the amount of light incident on the device which is transferred as output signal charge.
