Title: Metallisation system for semiconductive devices devices utilizing such metallisation system and method for making devices and metallisation systems
IPC: B23K35/00
Filed: 1974-12-18
Abstract: 1467339 Contacts for semi-conductor devices MOTOROLA Inc 18 Dec 1974 [3 Jan 1974] 54746/74 Heading H1K [Also in Division C7] A semi-conductor, e.g. Si or Ge, is heated to about 200‹ C., a layer of an alloy with the semiconductor is formed thereon, a layer of Al is formed thereover, the source of heat is removed, and the Al layer is coated with a layer comprising Al and Sn. A flash layer of Pd, Rh, or Pt may be overlaid on said Al-Sn layer. The process is useful in making Zener diodes, thus: a semiconductor 24, e.g. of Si having a P-type region 26 is coated with SiO 2  at 28 and windows 29 are etched therein; the article is placed in a vacuum coating apparatus, heated to 200‹ C., and Al is evaporated to an equivalent thickness of 2500 Š; some of this forms an Al-Si layer 51A, and the remainder forms an Al layer 51B. The heat source heating the article is turned off, and a heater activated to evaporate a source of Sn in the apparatus, the Al also continuing to evaporate whereby an Al-Sn layer 52, corresponding to 2500 Š of Al and 20,000 Š of Sn is deposited; this is overcoated by a layer 53 of Pd, Rh or Pt. The chip is inverted and the process repeated to give similar layers 54A, 54B, 55 and 56. A laser is used to break up the chip (at 23) into individual dice, which are then inserted into a cylindrical glass sleeve with a slug of contact metal, e.g. Mo, Co, Ni, Ag, Pt, Pd, Rh, W or alloy, at each face 53 and 56, and the whole assembly is heated to 725-825‹ C. to bond the die to the slugs and the slugs to the glass.

Title: A process for the production of hydrophobic fine-grained powders and/or granulates from waterglass
IPC: C01B33/32
Filed: 1966-12-09
Abstract: A granular composition is made by spraying a latex, for example Buna-Huls 220, into a granulating drum containing spray-dried water glass in the form of hollow spheres of bulk density 50-200 g./1. which have been rendered hydrophobic by treatment with a vaporous organic halogen silane, such as dimethyl chlorosilane. The latex is used in the amount of 10-50% by weight based on the dry weight of the hollow spheres.ALSO:Water-glass, spray-dried from aqueous solution, having the form of hollow spheres and a powder density of 50-200 g./l., is treated with vapours of organohalogen silanes and then heated for 30 minutes at 300 DEG  C.  The preferred organohalogen silane is dimethyl dichlorosilane, used in quantities of 2-20% by weight, based on the spray-dried waterglass.  The vapours of mineral acids, preferably hydrogen chloride, can be used in addition to the organohalogen silanes in order to completely neutralize the alkali in the waterglass.  The above-treated waterglass may be granulated by spraying with a latex emulsion in quantities of 10-50% based on the weight of spray-dried waterglass.  The above materials are suitable for adsorbing water-immiscible organic materials, e.g. oil, from water.

An entry rollway 4 for a cooling bed 2 comprises a series of rollers 6 with fixed intermediate braking plates 8 on the side remote from the cooling bed and vertically movable braking plate 10 on the side nearest the cooling bed which have tapered forward guides 20, 22, 24, 26, 28, 30 to deflect a rolled rod on to the fixed plates. The rods are fed from mill shears 18 and alternately separated by raising and lowering the braking plates 10. The plates 10 are raised by a reciprocable rod 32 connected to the plates by bell-cranks 34, 36, 38, 40. The rod 32 is divided into aligned parts 32a, 32b connected by hydraulic piston cylinder units 48, 50. When the units are pressurized the plates 10 are all raised together whereas when one unit is not pressurized the adjacent parts 32a, 32b are drivably disconnected so that only the plates 10 nearest the rod drive are raised. The number of plates 10 rendered inoperative is selected in dependence on the speed and length of the rods leaving the mill shear 18.
