Abstract
A shift array for shifting carriers introduced into a semiconductor body toward the X-direction and Y-direction comprises an insulating layer disposed on the semiconductor body, first electrodes disposed on the insulating layer and arranged in a matrix on the X-Y plane, second electrodes disposed between adjacent first electrodes, conductors disposed adjacent to the first electrodes to be connected to the electrodes of each row when carriers are transferred toward the Y-direction, conductors disposed adjacent to the first electrodes to be connected to the electrodes of each column when carriers are transferred toward the X-direction. When carriers are transferred toward the X-direction, the second electrodes disposed between the adjacent first electrodes of each column are biased with a DC voltage whose electrical polarity is reversed relative to the DC voltage applied to the first electrodes for preventing the transit of carriers toward the Y-direction. When carriers are transferred toward the Y-direction, the second electrodes disposed between the adjacent first electrodes of each row are biased with a DC voltage whose polarity is reversed relative to the DC voltage applied to the first electrodes for preventing the transit of carriers toward the X-direction.
