Title: Charge coupled circuits
IPC: H01L21/00
Filed: 1972-01-05
Abstract: 1377122 Charge coupled devices RCA CORPORATION 5 Jan 1972 [14 Jan 1971] 20039/74 Divided out of 1377121 Heading H1K A charge coupled device comprises a plurality of charge transfer paths defined by thin insulating layers supporting the electrodes the paths being separated by thick insulation on top of which extends a conductive track joining corresponding phase electrodes of the paths. As shown, Fig. 9, a plurality of parallel thin portions of an oxide layer on an N type Si substrate define charge transfer paths and are crossed at right angles by mutually insulated polysilicon electrodes 40-1b, 2b, 3b, 4b and Al electrodes 40-1a, 2a, 3a, 4a which zig-zag in opposite directions above thick portions of the oxide layer and are connected at their crossing points above these thick oxide portions. This results in the Al electrodes being arranged on opposite edges of the polysilicon electrodes in adjacent transfer paths so that the charges are shifted in opposite directions. This enables a long shift register to be provided by connecting the output of the first register path to the adjacent input of the next path. The use of polysilicon and Al electrode pairs connected to the same phase of the power supply produces an asymmetrical potential well. In a second embodiment, Figs. 12 to 14 (not shown), a plurality of polysilicon electrodes (65 to 69) extend at right angles to the charge transfer paths and overlapping Al electrodes (53 to 63) are provided in the form of stubs extending alternately to conductive tracks (50, 52) on the thick oxide on either side of each transfer path. Alternate tracks are connected to the same phase of the power supply and are connected to alternate ones of the polysilicon electrodes at the crossing points. The Al stubs forming the electrodes are staggered either side of each conductive track so that the shift direction alternates in the transfer paths. In an alternative arrangement, Fig. 16 (not shown), in which asymmetrical potential wells are generated by applying an offset voltage between electrodes forming a pair connected to a single phase of the supply, Al electrodes in the form of interdigitated fingers extend alternately to conductive Al tracks on the thick oxide layers.  Polysilicon electrodes extend across the transfer paths and thick oxide and alternate electrodes are contacted by tracks on the thick oxide. The electrodes are arranged so that when they are energized by a two phase supply with an offset voltage provided to the polysilicon electrodes the charges in all the transfer paths are shifted in the same direction and the parallel bits may constitute a byte of information. Methods of manufacturing the devices and alternative materials are also described-see abridgement of Specification 1,377,123.
