Abstract:
1. A method for producing an image sensor comprising an array of pixels that includes vertical charge-coupled device (VCCD) shift registers, the method comprising: forming a first layer of gate electrodes over the VCCD shift registers; forming a physical gap in the first layer of gate electrodes such that first and second sections of gate electrodes in the first layer of gate electrodes are produced and are physically separated and electrically isolated from each other; forming a second layer of gate electrodes over the first and second sections of gate electrodes in the first layer; and forming another physical gap in the second layer of gate electrodes such that first and second sections of gate electrodes in the second layer of gate electrodes are produced and are physically separated and electrically isolated from each other.
