Title: Imaging devices

Abstract: An imaging device includes a semiconductor body and a array of photosensitive elements arranged in rows and columns at a first portion of the body. A plurality of charge-transfer lines interdigitated with the columns of the array are provided for transfering storage charge carriers from the array to a charge-transfer shift register at a second portion of the semi-conductor body. Each of the transfer lines includes an elongate resistor electrode which has connections for applying a potential difference along the resistive electrode to produce a drift field in the underlying body portion in the direction of the shift register for transporting mobile charge carriers toward the shift register.
