As shown, the switch assembly includes two sets of series-connected resistors 41 and two isolated contacts 43 which are longer than the contacts 42. The rotor consists of metal plates 70 and 71 which contact elements 43 and carry tongues 72, 73 which make contact sequentially with the contacts 42. Substrate 1 carries an arcuate conductive track 6 which acts as a slip ring to carry current to the resistor track wiper (14, Fig. 2, not shown). The resistor chains may be connected in various ways to the track (Figs. 6 and 7, not shown) to provide stepped (coarse) and fine adjustments. The switch assembly may be mounted on the same substrate as the resistor track (preferably on the opposite side), and the substrates are preferably ceramic, e.g. alumina or beryllia, or of yttrium iron garnet. The resistor track may be formed by thick film, e.g. screening methods using a paste of a solvent, binder, glass and metal. The metal may be palladium/silver or platinum/ gold alloy, palladium oxide/silver, thallium or ruthenium. The thickness of the deposit is between 0À0005 and 0À0015 inch. For a thinfilm circuit, the substrates may be glasses or glazed alumina and the track applied by vapour or electroless deposition methods. A plastics (e.g. resin-bonded paper) substrate with a carbon track screened on to it may be used; alternatively the substrate may be conductive. The spindles may be non-conductive, the wiper contacts of metal or carbon brushes, and the resistor track a multi-turn device (see Specification 1,363,858).

Abstract: 1445586 Semiconductor devices; pick-up tubes WESTINGHOUSE ELECTRIC CORP 28 Sept 1973 [11 Oct 1972] 45428/73 Headings H1K and H1D A radiation sensitive charge storage target comprises a conductive support mesh formed by electroplating, and pillars of semiconductor material each containing a PN junction, located in the interstices of the mesh with one end of each pillar, standing proud of the mesh, provided with a contact formed by electroplating and of greater cross-section than the end of the pillar. A typical target is made by first oxidising the surface of a 10 ohm. cm. N type silicon wafer and reducing the oxide on one face to a mosaic of patches by photoresist etching. The exposed silicon is etched to form mesas under the patches, the oxide masking removed and the surface reoxidised. Resist is then spun over the etched face to provide an etch mask which is absent only at the sharp edges of the mesa tops. The exposed oxide is etched with sufficient undercut of the mask to lay bare the tops of the mesas into which boron is then diffused to form the PN junctions. After etching the opposite face to thin the wafer a gettering layer is provided on that face by phosphorus diffusion and the wafer annealed in hydrogen. Thin layers of titanium and gold are successively formed by evaporation over the patterned face, resist applied as before, and the exposed metal etched away with sufficient undercut to expose the mesa tops. After removing the resist the metal between the mesas is electroplated with gold to form a support grid from which the mesas project. The titanium and gold deposition steps and application of resist are then repeated and the wafer placed in a gold-plating bath to form contacts over and overhanging the edges of the mesas. After etching the back face of the wafer to separate the mesas, the remaining resist and underlying metal are removed and a transparent layer of gold deposited to form a common back contact for the mesas. In an alternative method facilitating etching control the mesas are formed in an epitaxial N layer or an N+ substrate.
