CHARGE-COUPLED IMAGING DEVICE

摘要

In charge-coupled imaging devices it is generally necessary to provide zones (12) in the matrix with a contact. These zones may form part, for example, of means for draining charge, for example as a protection against overexposure. In the case of imaging devices with a horizontal readout register on one side of the matrix, these contacts can be provided on the opposite side. However, it is often desirable or even necessary, as in the case of imaging devices with four-quadrant readout, to provide such contacts on the same side as the horizontal readout register. To this end, a dummy line (14'-17') is provided in accordance with the invention between the matrix and the horizontal readout register (6), said dummy line having an electrode structure which leaves room for contact windows (22) to the zones (12).
