Abstract: 1,069,579. Semi-conductor devices. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept. 27, 1965 [Nov. 11, 1964], No. 45896/64. Heading H1K. A body of binary semi-conductor compound, in which the conductivity type depends on one of the component elements being present in excess, is contacted by,depositing that element of the compound present in excess and a third element which is substantially inactive in the compound material and forms an alloy with the deposited element at a temperature below the melting point of the semi-conductor compound, and heating at a temperature below the said melting-point to form the alloy. In a specific example a body of GaAs of P- type conductivity by virtue of an excess of Ga is cleaned and masked, and a layer of Au is evaporated on to the exposed surface and covered with an evaporated layer of Ga. The body is heated in an argon-hydrogen atmosphere to form an Au-Ga alloy contact, said to be bonded to the body by virtue of the Ga content of body and contact. The " third element " used in the contact may be either neutral in, or of the same conductivity type as, the semi-conductor material and the contact materials may be deposited in any order or simultaneously.

Abstract: 1,202,084. Winches. PORTASILO Ltd. 20 Dec., 1968 [6 Oct., 1967], No. 45896/67. Heading B8B. [Also in Division F2] A winching arrangement for moving a scraper bucket between opposite ends of a boom, comprises run in and run out cables 32, 36 associated with winding drums 26, 27, one drum being selectively driven whilst the other selectively has a retarding force applied thereto during its movement in a cable unwinding direction, the retarding force increasing with increase in the speed of drum rotation. The retarding force is hydraulically applied to the relevant drum by an adjustable spring-loaded throttle valve situated in the return line of an associated hydraulic circuit including a reversible pump 61, 62 driven by the drum through a chain 58, 59. Both drums 26, 27 are freely mounted on a shaft 38 chain driven from a motor 28, and each is drivingly connectible thereto through an hydraulically operated clutch, the hydraulic circuits associated with the arrangement being supplied from an hydraulic reservoir 52. Solenoid-operated valves W, X, Y, Z controlling the sequence of bucket operation are controlled by switches 69, 71 actuated by a cam 68 which is driven through a reduction gear 67 from the shaft 66 of pump 61. In operation, the drum 26 is driven to cause the bucket to scrape material while the drum 27 pays out freely, the throttle valve being brought into operation to retard the drum 27 as the bucket approaches the end of its inward run, whereupon the bucket is lifted and tilted for emptying. The drive is next transferred to the drum 27 while the pay out of the drum 26 is retarded to prevent oscillations of the bucket and hold it up adjacent the boom as it moves to the outer end thereof. At the boom outer end, the bucket is lowered to the ground for another cycle, by the drive to both drums being disconnected and a disc brake 63 being applied to the pump 61 and hence drum 26, and the drum 27 paying out against the retarding force. A bucket parking condition is provided for in which both drums are disconnected from the drive and disc brakes 63, 64 applied to both.

Title: Enhancement of diffusion of atoms in a heated substrate by bombardment
IPC: H01L21/00
Filed: 1970-10-01
Abstract: 1320555 Semi-conductor devices J F GIBBONS 1 Oct 1970 [15 Oct 1969] 46760/70 Heading H1K To facilitate diffusion of atoms in a semiconductor it is heated to a temperature at which lattice vacancies and interstitial atoms can move freely e.g. to 450-700 C. in silicon and 360-500 C. in germanium while being bombarded with a beam of particles to create vacancies. The technique can be used for annealing silicon-silicon oxide interfaces, to relocate boron atoms introduced by ion implantation and to accelerate inward diffusion of impurities such as Cu, Au, Pt, Li, Cr used to reduce carrier lifetime or to increase resistivity by compensation. Its main use is however to facilitate localized in-diffusion of donor and acceptor impurities. Localization is effected by focusing the beam of particles which may be protons, neutrons, electrons, or alpha particles or by masking with metal or thick oxide to define areas to be treated. To form an ohmic contact or PN junction a layer of appropriate impurity is deposited and treated e.g. for ¢-1¢ hours, the impurity profile being controlled by variation of dose rate, particle energy and treatment time. Superposed PN junctions are formed by simultaneous or successive diffusion of donor and acceptor atoms. In treating A III B V  and A II B VI  compounds volatilization of the constituent atoms during treatment is avoided by overcoating the impurity beforehand with oxide. To form a field effect transistor in N type silicon the process is used first to form a P type region and then to form P + source and drain inclusions. A further treatment can be used to form an N type gate region or oxide and an overlying metal gate between the inclusions.
