Title: A semi-conductor device
IPC: H01L21/00
Filed: 1962-03-05
Abstract: 979,465. Semi-conductor devices. SIEMENS SCHUCKERTWERKE A.G. March 5, 1962 [March 28, 1961; June 24, 1961; July 7, 19611, No. 8479/62. Heading H1K. A transistor, rectifier, or photo-electric element comprising a semi-conductor body mounted on a carrier plate having substantially the same coefficient of expansion is secured to an electrode by clamping the carrier plate to the electrode. A P-type silicon disc 5 is assembled in a pile with an aluminium disc 4 and a molybdenum carrier plate 3 on one side and a gold antimony foil 6 on the other side. The assembly is pressed into a non-melting powder which does not react when heated to 800 C. under pressure in a protective gas or a vacuum. When the assembly has fused sufficiently to provide a PN junction in the silicon and to combine as a unit, at least that portion exposing the PN junction is etched and the assembly is coated with an oxide. The top of a pedestal 2a on a copper mounting block 2 is coated with gold or silver or an alloy of these and the coating is lapped as is the bottom surface of the molybdenum disc 3. A dished steel clamping ring 11  engages the periphery of the molybdenum disc 3 and is drawn downwards by bolts 13 engaging an overlying clamping ring 12. The height of the clamping ring 11 is such as to give the same expansion as the molybdenum disc 3 and copper pedestal 2a combined. A copper plunger 7 provides the second electrode and its contacting face is lightly grooved, silver coated, and lapped. The gold-silicon eutectic on the top of the silicon disc is also lightly lapped. The plunger 7 is centred by a closely fitting washer 8a spaced from a larger washer 8b by means of ceramic or heat resisting lacquer 8c. Dished spring washers 9 and 10 are compressed by the clamping ring 12 to hold the plunger 7 in contact. A cover comprising the ferrous parts 14 and 16 separated by a ceramic portion 15 is soldered to a terminal connector 17 and is secured to the block 2 beneath a turned over peripheral lip. Instead of securing the clamping rings by means of bolts 13 they may be secured by turning over a second lip raised from the copper block 2 (Fig. 2, not shown). Alternatively, as shown in Fig. 4, the clamping rings may be replaced by a single clamp 26 secured under the same swaged lip that secures the cover. In this instance the lip is formed as part of a hard steel ring 27 soldered to the copper block and the clamp 26 is force fitted into an under-cut recess at the root of the lip. An alternative terminal plunger 28 is also shown in Fig. 4 and comprises a head faced with a molybdenum disc 30. The plunger 28 is centred by a mica disc 32 and is held by three spring washers 34, 35, and 36. The silver coating on the top of the copper pedestal 2a may be replaced by a loose silver disc, with honey-combed faces that has been heat treated and etched in nitric acid, or by a fine silver wire mesh bedded in a graphite powder. The carrier plate may be of tantalum.

Abstract: 902,769. Seaming, non-metallic sheet material; laminates and laminating. BLEIWARENFABRIK GUMPOLDSKIRCHEN A.G. March 11, 1960 [March 12, 1959; March 23, 1959; Dec. 14, 1959], No. 8739/60. Classes 42 (1) and 140. A method of heat-sealing thermoplastic members comprises heating at least one metallic means to a heat-sealing temperature which is at least equal to the softening temperature of the plastic members to be heat-sealed, then inserting said metallic means while at said heatsealing temperature between the plastic members and compressing the plastic members and the inserted metallic means to bond them together. For heat-sealing two plates 1 and 1<SP>1</SP> of polyethylene or polypropylene lying in the same plane, with a butt joint, they are engaged at the edges 8 and are superimposed with a perforated metal strip 5 heated to the liquefying temperature of the plastic and with a further plastic strip 6, whereafter the parts are pressed together. The metal used may be iron, steel, brass, lead, copper, or aluminium, and may be in the form of bars, wires, wire fabric, or perforated or expanded sheet. The invention may also be used to join flanged members together to form a container and for making reinforced plastic panels. In the latter application (Fig. 11), two plastic webs or plates 41, 41<SP>1</SP>, e.g. of polyethylene or polypropylene are withdrawn from supply rolls and fed between guide rollers 42, 42<SP>1</SP> to a preferably thermostatcontrolled preheating device 43 or 43<SP>1</SP>. At the same time a perforated metal web 44 of steel, aluminium &c. is fed between the rolls 41, 41<SP>1</SP> by means of pairs of rollers 45, 45<SP>1</SP> to a heating device 46 which heats the metal web to a temperature somewhat above the liquefying temperature of the plastic. The two plastic webs with the metal web therebetween are then fed to the nip between pressure rollers 49, 49<SP>1</SP> where the webs 42, 42<SP>1</SP> liquefy, at least in the zones which adjoin the metal web 44, so that a reinforced plastic web emerges. The web is cooled by air or water sprayers 50 and is passed through pairs of rolls 52, 52<SP>1</SP> which smooth the surface of the web. In a further embodiment, reinforced plastic tube lengths are produced by applying plastic webs to both sides of a metal web in the form of a tube.
