CCD array with integrated high voltage protection circuit

摘要

A CCD containing circuit and method for making the same. The circuit includes a CCD array and a protection circuit. The CCD array is constructed on an integrated circuit substrate and includes a plurality of gate electrodes that are insulated from the substrate by an insulating layer. The gate electrodes are connected to a conductor bonded to the substrate. The protection circuit is also constructed on the substrate. The protection circuit is connected to the conductor and to the substrate and protects the CCD array from both negative and positive voltage swings generated by electrostatic discharge events and the like. The protection circuit and the CCD can be constructed in the same integrated circuit fabrication process.
