Abstract: 308,838. I. G. Farbenindustrie Akt.- Ges., (Assignees of Skutezky, R.). March 30, 1928, [Convention date]. Plastic compositions containing amorphous cellulose.-Viscose which may contain added vegetable fibres is formed into a sponge by incorporating as core forming material salts capable of reacting with alkali, such as ammonium or acid salts or mixtures of these with neutral salts, one or more of which may contain water of crystallization. Conditions may be adjusted so that the decomposition of the xanthate is produced by after treatment or by the salts conveniently with the coagulation. The Specification also describes the use of mixturs of hydrated and anhydrous neutral salts. The escape of water from the cellulose structure may be prevented independently of the nature of the pore forming fillers by heating in an atmosphere which may be under pressure or saturated with water vapour. In an example 160 grams of viscose (up to 10 per cent cellulose) containing if desired, colouring material, are mixed with 16 grams cotton, hemp, flax or like fibre, and 1.2 kilograms of a mixture of crystallized sodium sulphate and ammonium sulphate (or ammonium bisulphate or sodium sulphate), moulded and allowed to stand at 180‹ C. for half an hour to three hours.

Title: Improved method for the production of semi-conductor devices of npn or pnp type
IPC: H01L21/18
Filed: 1955-04-07
Abstract: 805,493. Semi-conductor devices. TELEFUNKEN G.m.b.H. April 7, 1955 [April 7, 1954], No. 10205/55. Class 37. A method of forming a semi-conductor device or NPN or PNP type having a very thin middle layer of a few microns thickness and a high limit of frequency, comprises arranging in juxtaposition a foundation of semi-conductor material of one conductivity type and a quantity of a second semi-conductor material of the same conductivity type, at least one of the materials containing both donor and acceptor impurities, the impurity in and determining the type of conductivity of the foundation material having a lower segregation constant than any of the impurities in the second semi-conductor material characteristic of the opposite conductivity type. The materials are heated to cause the second material to be fused to a surface of the foundation, and thereafter they are cooled so that solidification commences at the surface of the foundation and proceeds in a monocrystalline manner to form a layer of opposite conductivity at the junction of the two materials. It is preferable that the semi-conductor foundation material should have a higher melting-point than the material to be fused thereto, or it must be arranged that the foundation material remains solid during the process of alloying. The foundation material may be melted in a protective gas or a vacuum. The apparatus for forming the device comprises a carbon or quartz piston and cylinder, Fig. 1, the piston being cooled and the cylinder heated. In one combination of materials for example, a slab of foundation material 13 of N-type silicon containing antimony is etched and fixed to the piston, and a grain 11 of N-type germanium containing a minority of acceptor material such as aluminium is melted on to the bottom of the cylinder and spread by downward movement of the piston to form a layer 14. The slab 13 is kept at the same temperature as the layer 14 so that a quantity of the germanium may then dissolve in the fluid phase of the silicon. Thereafter the foundation 13 is cooled from the top to produce layers 15, 16 and 17, Fig. 2, according to the impurity segregation constants, which layers are P-type silicon containing aluminium, intrinsic, and N-type germanium with a strong excess of antimony. By increasing the excess of antimony in the germanium the transition in the layer 16 from the P-type conductive to the N-type conductive material will take place sooner, furthermore the thickness of the P-type conductive region can be made thinner by providing a smaller quantity of antimony in the grain 11. In addition a thinner P-type conductive region is formed at lower alloying temperatures because with increase in temperature more silicon goes into solution. Other examples of suitable materials are shown in Fig. 3.
