Title: Method of vapour depositing a material in the form of a pattern
Inventor: JACKSON THOMAS MEIRION
IPC: C23C14/04
Filed: 1966-10-17
Abstract: 1,138,556. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd. 17 Oct., 1966, No. 46294/66. Addition to 1,138,084. Heading H1K. [Also in Division C7] In a vapour deposition process of forming a pattern of a first material such as Cd on a first substrate, e.g. cellular Si, the first material is evaporated from a layer of said material on a second substrate in juxtaposition to said first substrate by focusing a converging beam of intense radiant energy, e.g. a laser beam, on to the second substrate which consists of a film of a second material, such as Ta, which has a higher melting point than the boiling point of the first material, supported on a base such as glass, the required pattern being formed by relative movement of the substrates with respect to the focus of the radiant beam. As shown in the Figure infra-red radiation from a laser is directed and focused via mirror 1 and compound lens 7 on to the layer 5 of Ta on glass sheet 4. The heat generated in the Ta layer is conducted to the contiguous Cd layer 6 which is evaporated and condensed on the first substrate 3 located on the co-ordinate table 2 which is moved during deposition to produce the required pattern. The deposited pattern forms the interconnections between the devices in an integrated circuit.

The immersion time in the melt is 0À1-4 secs. to form a coating 0À5-5 microns thick and the melt is preferably at 950- 1100C when it contains 3-5 atomic % Nb. With Nb and Ge in the melt the melt composition is preferably Al 69  Ge 30  Nb. The Nb in wire or strip form is passed through a melt 6 contained in a ceramic crucible 5 in a Mo container 2 which is enclosed in a tube 8 surrounded by a HF coil 14 and protected by an inert gas. An annealing tube is connected to the tube 8 so that coating and annealing are effected in sequence.

Abstract: 1424609 Clutch release bearings; friction clutches SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 12 Oct 1973 [14 Oct 1972] 47813/73 Headings F2L and F2C] In a combination of a clutch release bearing 1 and a clutch release lever 10, the bearing has a curved surface to co-operate with a curved surface of the release lever, one surface being convex and the other concave, the concave surface having a greater radius of curvature than the convex surface. As shown the bearing has the concave surface and the lever the convex surface, but this may be reversed (Fig. 2, not shown). The curved end face of the bearing may comprise a graphite or plastics ring. The difference in the radii of curvature gives the bearing a self centring action as the convex surface moves to the bottom of the concave surface, some radial play being present between housing 4 and the races 5, 8 to allow this. The lever 10 may be a tongue of a diaphragm spring of a diaphragm spring clutch.
