Title: Improvements in and relating to the manufacture of semiconductor devices
IPC: H01L21/00
Filed: 1960-01-15
Abstract: 936,333. Semi-conductor devices; plating semi-conductors. PHILCO CORPORATION. Jan. 15, 1960 [Jan. 16, 1959], No. 1531/60. Classes 37 and 41. In a method of making a semi-conductor device comprising jet electroplating an indium electrode on a germanium body and subsequently alloying the electrode to the body, the plating solution contains an indium salt and 0.01 to 0.1 grams per litre of a soluble lead salt to prevent deformation of the plated electrode during alloying. In an example, using a solution containing 38.4 grams per litre indium trichloride, 0.015 grams per litre lead dichloride, and 0.040 grams per litre of sodium butyl sulphonate or decylbenzene sulphonate, an electrode may be plated in 4 seconds by passing 1 milliamp of plating current and 24 ml/sec. of plating solution through a 6.9 mil. jet. The preparation of the plating solution which is described in detail involves preparing separate solutions of the three components, mixing two of these, diluting and adjusting the pH value to 2.2-2.5, and finally adding the alkyl sulphonate solution immediately before use. Specifications 824,484 and 894,708 are referred to.

Abstract: 1,086,751. Moulding buttons &c. S. EMSIG, J. EMSIG, and J. R. SUCHER, [trading as EMSU CO.]. Jan. 13, 1965, No. 1545/65. Heading B5A. A plurality of articles, e.g. buttons, are moulded by heat and pressure between two relatively movable mould halves 21 and 22, a stretchable film 34 and a porous sheet 35, of e.g. paper or fabric, being interposed between mould half 21 and the working material 33 (a liquid polyester resin). Closure of the moulds forces the working material, the film, and the porous sheet into the cavities 40, the porous sheet acting as a duct to remove any trapped air, this facilitating an accurate reproduction of each mould cavity. The film and sheet are subsequently removed from the finished article. The porous sheet may be ruptured during the process and may, in fact, comprise discrete areas, e.g. material rather than a continuous sheet. As shown in the Figure, a resilient layer 30 of e.g. cardboard and a liner 31, preferably carrying a release agent, may be interposed between non-cavitied mould half 22 and the working material.
Patent GB-483406-A (GB)
Title: Improvements in or relating to methods for the production of reactive hydrogen
IPC: C01B3/00
Filed: 1937-01-19
Abstract: Reactive or atomic hydrogen is obtained by the alternate formation of a hydride of the alkali or alkaline-earth metals and its subsequent decomposition to form the metal and reactive hydrogen.  For example, lithium hydride may be formed by treatment of the metal with hydrogen, e.g. at 500-700 DEG  C., or by reaction of lithium nitride with hydrogen, and is subsequently decomposed by heating or by electrolysis in the molten state.  The hydrogen used should be free from oxygen, air, moisture or other substances liable to reconvert atomic into molecular hydrogen, and if desired may first be passed through an accumulator formed of sheets of metals which readily occlude hydrogen, e.g. palladium.  The reactive hydrogen readily reduces oxides, sulphides and halides to metal, e.g. magnesium sulphide to magnesium, and may be used for hydrogenation processes. Specification 482,157, [Group II], is referred to.
