ABSTRACT:
A CCD device includes multiplication elements arranged so as to multiply charge by clocking with a high voltage. An additional region beneath the high voltage electrode is so doped in relation to at least the preceding electrode as to have a higher depleted charge density than under the preceding electrode. This assists in preventing high energy electrodes from encountering the silicon surface of the semiconductor.
