Abstract

942,406. Semi-conductor devices; television pick-up tubes. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 21, 1960 [Dec. 24, 1959], No. 43904/60. Headings H1D and H1K. The target of a television camera tube is composed of a mosaic of NPN semi-conductor elements, Fig. 2, the thickness of the P domains being smaller than the effective diffusion length of the minority carriers (electrons) in these regions. The base layer N is only interrupted at its front surface and is in contact with a signal electrode consisting of a thin transparent metal layer. The production of hole-electron pairs in the base layer by the radiation quanta falling upon produces an electron current through the semi-conductor proportional to the number of hole-electron pairs. The restoration of a mosaic element to cathode potential by the scanning beam produces an instantaneous voltage difference across the signal resistor. The target may be cooled to reduce the dark current. In Fig. 4 the tube incorporates a mirror optical system 12, the window 4 serving as a correction lens. A cooling vessel 11 is associated with the target. The mosaic elements of the target may be produced by etching N and P-type layers through a mask prepared by a photographic process or by depositing impurity atoms in the interstices of the mask from a flowing gas. The mask, e.g. silicon oxide, may be retained in position to protect the base layer from direct bombardment by the scanning beam. A suitable material for the base layer is silicon or germanium and the impurity atoms may be arsenic and boron or phosphorus and gallium.
