Abstract: 1,244,225. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 31 Dec., 1968, No. 61953/68. Heading H1K. A continuous conductive layer 23 is provided over the surface of a semi-conductor body while it is being subjected to ion implantation so that the entire surface is maintained at a common potential. The layer 23 is then removed without removing the underlying body or electrodes &c. thereon. Fig. 5 shows a stage in the manufacture of a P-channel Si IGFET having two gate electrodes 14, 15 overlying respective channels 16, 17 which are joined by an intermediate N-type region 9. The device is formed in a P-type epitaxial layer 2 on a P + substrate 1. Source and drain regions 5, 7 are provided by diffusion of phosphorus, and the various electrodes 11, 12, 14, 15, which have a complex geometry (Fig. 1, not shown), underlie the conductive layer 23 and act as masks against the phosphorus ion implantation which forms the intermediate region 9 and the peripheral portions 6, 8 of the source and drain regions. In modifications the intermediate region 9 may be partly formed by diffusion or the source and drain regions may be entirely formed by ion implantation. The conductive layer may be held at the substrate potential, e.g. earth, by means of a metal clip or by the provision of an aperture in the oxide layer 4, which aperture may have a grid-like shape, each element of the grid surrounding an individual transistor in a large wafer. The electrodes 11, 12, 14, 15 and the layer 23 may all be of Al, the layer 23 being ultimately removed by light etching. Alternatively the electrodes may be of Au on Mo while the layer 23 is of Ti. In a further modification a continuous Ti layer is applied prior to application of Au on Pt electrodes, and after implantation only the exposed portions of the Ti layer are removed. The invention is applicable to complex electrode geometry IGFETs other than the tetrode form illustrated, and may also be used in the manufacture of bipolar transistors or integrated circuits.

Title: Vertical colour boundary crispening circuit for solid state colour television cameras
IPC: H04N5/30
Filed: 1978-07-06
Abstract: To correct vertical edge blurring in elemental-area sampling type imagers a signal processor interpolates to define intermediate signal levels between the samples, this being carried out by delaying 42 a colour signal for a sample period, substracting 43 the delayed signal from an undelayed signal for the same colour and then integrating 44 the difference signal. In colour imaging on a single chip the sampling occurs at different times for different colours and the sampling frequency is frequently different for different colours, so that the colour signals exhibit sharp transitions at the boundaries of picture elements. The luminance is most closely represented by the green signal, and two 'slow' green signals Gs1, Gs2 are produced from alternate green samples and averaged 50 and then added 52 to the full green signal GF to enhance high frequency detail YH. <IMAGE>

Title: Controlling the continuous casting of metals
IPC: B22D11/16
Filed: 1979-01-17
Abstract: A signal S representing the frictional forces arising between the strand and the oscillated mould during a continuous casting operation is provided by selecting according to at least two frequency bands, e.g. 0.2 to 3 Hz and 3 to 10 Hz, the constituents of a signal, e.g. from a mould-movement sensor, representing the frictional forces. The signal S is preferably a signal representing the ratio of the demodulated constituents. Any abnormal behaviour of at least one of a plurality of continuous casting factors, particularly those related to the covering material on the liquid metal and its various functions, is detected by comparing the signal S with an analog- type reference signal considered as ideal for satisfactory casting. Casting factors such as tundish and mould conditions including metal temperature and level, pouring tube position, mould oscillation, cavity taper and cooling aid secondary cooling, withdrawal speed and roller pinch may be mentioned. The abnormal behaviour is corrected by modifying the factor concerned possibly automatically, at least in part, so that the signal S comes as close as possible to the reference signal. <IMAGE>
