Title: Improvements in or relating to methods of manufacturing semiconductor devices
IPC: H01L21/00
Filed: 1961-03-09
Abstract: 956,033. Making semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. March 9, 1961 [March 12, 1960], No. 8665/61. Heading H1K. Material to be alloyed to a semi-conductor body is held apart from the body in a centrifuge and is released in a molten state during operation of the centrifuge so that it is thrown on to the body at high speed. The centrifuge drum 4 is arranged within a closable vessel 1 in which a suitable atmosphere (e.g. hydrogen or inert gas) may be maintained, and the temperature of which is controlled by element 7. A number of jigs 8 are arranged on the inner wall of drum 4. In one embodiment (Fig. 2) a jig comprises a body 10 of graphite or chrome iron, rotatable about shaft 13 against spring 16. The jig tilts downwards as the speed of rotation increases, and at a certain speed molten material 18 (In, Al, Pb, Sn, Bi, Ga, B, P, As, Sb or alloys thereof) is able to leave space 17 and is thrown on to semi-conductor body 20 thus forming an alloy contact. A modification is also described in which the jig moves horizontally. In another embodiment (Fig. 4) molten material 35 is arranged at one end of a narrow aperture 36, the cross-section of which is selected so that material 35 passes through the aperture only when a certain speed of rotation is attained. In a modification (Fig. 6, not shown) the centrifuge is rotated at a constant speed and the temperature is raised until the material can pass through the aperture. In a further embodiment (Fig. 5, not shown) the material is arranged at the bottom of a slope up which it can travel when the speed of rotation is sufficiently great. The angle of the slope may be reduced a short distance above the starting point to reduce the dynamic resistance to movement. A further reduction may be achieved by coating the jig surfaces with soot or silicon oxide. A further embodiment is described in which the instant of release of the material is determined by external means. A centrifuge drum 70 (Fig. 8) is surrounded by a ring 75 rotatable within limits relative to the drum. The drum and ring are initially rotated together and a predetermined time a brake shoe 77 is moved to retard ring 75. Studs 74 on the ring then act on arms 73 on jigs 71 and rotate them about shafts 72 from the position shown in Fig. 9 to one in which material 79 can leave space 80 (Fig. 10, not shown). A plurality of alloyed regions may be formed, using any of these embodiments, on a single semiconductor body either by masking part of the semi-conductor surface, or by using a jig containing a number of pieces of material to be alloyed to different parts of the body and arranged for release at different speeds of rotation or different temperatures.

Filed: 1916-03-13
Abstract: 104,989. Wilzin, A. March 13, 1916. Gathering molten metal.-In a suction head for a glass-blowing machine, in which the molten glass is gathered by suction, the cross-sectional area of the suction passage is automatically reduced towards the completion of the suction period as the molten glass rises in the parison mould towards the neck mould. The plunger 35 that co-operates with the neck mould 29 is kept longitudinally shifted out of its normal moulding position by a spring 39 surrounding the plunger rod 34. A piston 33 also surrounds, and is secured to, the rod 34 and slides in the cylindrical suction head 25. A passage of large sectional area is left between the plunger 35 and the neck mould, and the harmful effect of leakage of air is diminished. As the glass is sucked into the parison mould 46 and rises towards the neck mould, tha pressure of the atmosphere overcomes the spring 39, and the plunger moves down to its normal moulding position, shown in dotted lines. Specification 104,722 is referred to.

Abstract: 1,013,826. Television. PYE Ltd. March 8, 1963 [March 8, 1962], No. 8872/62. Drawings to Specification. Heading H4F. In a television camera control circuit a peak white pulse is added to the camera output signal during the line blanking period and the combined signal is applied through an amplifier channel including a gain control stage at the output of which the signal is clamped with input to the peak white level. The arrangement permits the black level set up to be varied by adjustment of the gain of the gain control stage without any adjustment of the camera iris diaphragm becoming necessary to maintain the white level. The added pulse is removed from the final signal by a clipping and blanking insertion circuit. The pulse appearing at the output of the main amplifier may be compared with the original pulse in a gate stage and employed to control an automatic-gain-control stage so as to stabilize the channel gain. In another embodiment the peak white pulse is added to the camera signal at the input of the gain-control stage and the automatic-gain-control feature is omitted.
