DEFINITION

Classification: 438/60

Charge transfer device (e.g., CCD, etc.):

(under subclass 59) Process for making a charge transfer device having combined therewith another electrical device or element, either of which being responsive to electromagnetic radiation.

(1) Note. A charge transfer device is a structure in which storage sites for packets of electrical charge are induced at or below the semiconductor surface by an electric field applied by serially arranged gate electrodes formed thereupon and wherein carrier potential energy per unit charge minima are established at a given storage site and such minima are transferred in a serial manner via an active channel region to one or more adjacent storage sites.
