Abstract
The present invention involves a semiconductor device, such as a shift register, wherein information in the form of charge carriers is moved laterally through the bulk of a semiconductor layer by means of an electric field, while the charge carriers are stored at the surface of the semiconductor layer. According to this invention, information containing regions can be separated from each other by depletion zones extending through the thickness and the width of the semiconductor layer. Charge transport laterally through the interior of the semiconductor layer results in a considerable reduction of the transport time. Majority charge carriers are advantageously used.
