Abstract
An intensified charge-coupled image sensor comprises an image intensifier section and a header assembly. The image intensifier section includes an envelope having therein a photoemissive cathode for emitting photoelectrons in a pattern corresponding to the intensity of radiation incident thereon. The header assembly includes a charge-coupled device with a front surface having a plurality of electrodes adjacent thereto and a back surface directed toward the cathode. The charge-coupled device is improved by forming it on a disc-shape semiconductor wafer having a center portion and an annular rim portion, the center portion has a thickness less than that of the annular rim portion. A plurality of contact pads are formed around at least a portion of the rim portion. The contact pads are electrically connected to different ones of the plurality of electrodes.
