Title: Charge coupled circuits
IPC: H01L21/00
Filed: 1972-01-05
Abstract: 1377124 Charge coupled devices RCA CORPORATION 5 Jan 1972 [14 Jan 1971] 20041/74 Divided out of 1377121 Heading H1K In a charge coupled device utilizing a two phase clock supply, asymmetrical potential wells are produced by utilizing electrode pairs connected to the same phase of the clock supply but having a direct offset voltage therebetween. As shown, Fig. 4, alternate polysilicon electrodes 30-1b, 2b, 3b and Al electrodes 30-1a, 2a, 3a, 4a are provided on an N-type silicon substrate, the edges of the Al electrodes overlapping the edges of both adjacent polysilicon electrodes. Each Al electrode and one of the polysilicon electrodes it overlaps form an electrode pair which are connected to the same phase of the two phase supply but are arranged to have a direct offset voltage between them, provided for example by feeding them from appropriate tapping points on a potential divider in the two phase power supply. The offset voltage ensures that in each electrode pair the potential well below the polysilicon electrode is deeper than that below the Al electrode so that the two phase supply produces a unidirectional charge transfer. In a practical arrangement, Fig. 6 (not shown), a plurality of charge transfer paths are defined by thin oxide layers flanked by thick oxide, the Al electrodes are in the form of interdigitated fingers and the polysilicon electrodes are individual to the transfer paths and extend alternately to two conductive Al tracks outside the Al electrode connection tracks for connection to the offset drive supplies. In the above described arrangement the distance between the active part of each polysilicon electrode and the connection point to an Al track is kept short to prevent delays due to the polysilicon strip acting as a distributed RC transmission line but in an alternative arrangement, Figs. 7 and 8 (not shown), interdigitated polysilicon electrodes connected by a long polysilicon line extending parallel to the transfer path are capacitatively coupled to an overlying Al line connecting the Al electrodes driven by the same phase of the power supply (but having a D.C. offset) so that the propagation speed of the pulses along the polysilicon line is increased. The insulation between the polysilicon and the Al tracks is made thin and a material of higher dielectric constant may be used or a very thin layer of doped oxide which forms a junction with the polysilicon to block conductive paths through pinholes may be used. Such an arrangement can be applied to a plurality of parallel registers with alternate transfer directions in adjacent paths, Figs. 9 and 10 (not shown). Methods of fabricating the devices are described (see abridgement of Specification 1,377,123). It is mentioned that the invention may be applied to random access memories, and self-scanning photo-detector arrays.

[Classes 39 (i) and 40 (v).] A short wave generator has a cathode emitting electrons in a stream and means for causing the electrons in their passage to the anode to cross the following stream so that the interference produces high frequency oscillations. As shown, the linear stream 6 produced by the cathode 2 is deflected by a circular electrode 4, which may be part of the envelope or a metal coating, so that it crosses its path in its passage to the anode 8 mounted in an insulating bushing 9. The oscillation frequency increases with the anode voltage. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a valve of the magnetron type in which at a critical voltage on the anode the path of the electron stream is a cardioid.

Abstract: 1404096 Cobalt containing acicular ferrimagnetic iron oxide BAYER AG 27 April 1973 [29 April 1972] 20162/73 Heading C1A The production of acicular ferrimagnetic γ iron oxide containing 0À5-10 atom per cent of Co comprises tempering by heating at 600-800‹ C. cobalt containing acicular iron (III) oxide hydroxide or oxide and then subjecting the product to reduction and optionally re-oxidation to form ferrimagnetic α iron oxide with reduced remanence loss. As an example cobalt containing acicular α FeOOH is prepared by precipitating basic Co containing iron sulphate at a pH of 4À5-6À5 by adding NaOH solution and oxidizing the deposit into α (Fe, Co) OOH seeds by introducing air into the suspension heated to 55‹ C. The required pigment is formed by further oxidation of the suspension with air at 60-70‹ C. in the presence of additional NaOH solution and Fe and Co sulphate solution and then separated by filtration. This was dehydrated to α (Fe, Co) 2 O 3  by heating at 360‹ C. for 1 hr. prior to tempering at 600-800‹ C. for about 1 hr. Reduction and optionally seesudation yielded ferrimagnetic γ iron oxide with reduced remanence loss of approx. 10% after 30 mins. at 150‹ C.
