Abstract
1,250,740. Image pick-up tubes; semiconductor targets. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 12 March, 1970 [15 March, 1969], No. 8299/71. Divided out of 1,246,260. Headings H1D and H1K. The target of a camera tube comprising an N-type semi-conductor substrate provided with a mosaic of P-type regions and with insulation between the regions, is characterized by the provision of a resistive layer formed of chromium oxide or a mixture of chromium oxide and nickel oxide having a resistance of 10<SP>12</SP>-10<SP>16</SP> ohms per square. In order to avoid capacitive effects the resistive layer should preferably be interrupted where it overlies the centres of the P-type regions. Electrode processing.-A layer mainly consisting of chromium may be vapour-deposited from a chromium nickel spiral, the substrate being at about 200 C. The target is then heated, e.g. to 400 C., in an oxidizing atmosphere (air), e.g. for ¢ hour. The thickness of the coating is about 0À05 microns or less and its resistance depends on the temperature and duration of the oxidation process. In order to provide gaps in the coating over the P-type regions, the deposition may be made through a grating of parallel wires which covers these regions; the vapour deposition is performed in two different processes between which the grating is rotated through 90 degrees.
