Abstract

1439879 Charge transfer devices WESTERN ELECTRIC CO Inc 3 May 1974 [7 May 1973] 19463/74 Heading H1K A charge transfer device comprises a twodimensional array of electrodes 12, shown in Fig. 1 arranged in rows and columns on an insulative layer 11 overlying a charge storage medium 10, wherein conductive paths 13, 14, 15 are formed by coupling together into a series electrodes 12 each from a different row and a different column and wherein any three adjacent such series of electrodes are coupled to different conductive paths, whereby under appropriate biasing conditions of the conductive paths mobile charge carriers may be transferred along either of the transfer paths defined by the rows or columns of the array. The arrangement permits serial-to-parallel and parallel-toserial conversion during information processing such as time division multiplexing. As shown the asymmetric potential wells under each electrode are established by fixed charge regions 16, of the same conductivity type as the semi-conductor medium 10 and formed by ion implantation, at the “back” edge of each electrode. Alternatively, the asymmetrical potential wells may be formed by opposite conductivity type fixed charge regions under the “front” edge of each electrode. According to the potentials supplied to the electrodes by the clock means 39 the charge carriers can be transferred in either a horizontal or vertical direction between the regions under adjacent electrodes. In a second embodiment, Fig. 2, the electrodes comprise diagonally overlapping squares with the input electrodes 29 and the corresponding output and gate electrodes, 30, 31 respectively, all being enclosed within a channel stopping region 32. The conductively connected CCD principle may be used to improve transfer efficiency by providing heavily doped opposite conductivity type fixed charge regions in the storage medium in the gaps between electrodes along the charge transfer paths, Fig. 6 (not shown). Also to prevent charge diffusing to an adjacent electrode of the same conductive path small strips of channel stopping regions (P++– type) may be provided as a buffer between the electrodes.
