Abstract: 1,190,554. Circuit assemblies. INTERNATIONAL COMPUTERS Ltd. 15 Nov., 1967 [3 Dec., 1966], No. 54214/66. Heading H1R. In a circuit assembly in which electrical components are interconnected by a conductor arrangement including a plurality of conductor layers interleaved with electrically insulating layers at least one of the insulating layers is formed from a hard polyimide film. A substrate 1 of sintered alumina ceramic, glass, silicon or insulated aluminium has a set of supply conductors 3 for connecting power supplies to integrated circuit chips 2 formed thereon by depositing a coating of gold in a glass matrix through a silk screen and then firing the coating. An insulating layer 4 of a glaze or polyimide film is then deposited over the conductors 3 and substrate 1 and is so patterned to produce a matrix of apertures 5. The return path of the supply currents is completed by the deposition of a ground plane 6 produced by screen printng on the vacuum deposition of gold so that the ground plane 6 is provided with apertures corresponding to apertures 5 and projections 7. After the deposition of a further insulation layer 18, similar to layer 4, over the ground plane 6 a set of parallel signal conductors are formed by the vacuum deposition of gold through an apertured mask. A further insulating layer consisting of a thin film of polyimide is then formed over the signal conductors 8 by applying a coating of the polyamic acid dissolved in dimethyl formamide, centrifuging the coated structure, drying and then curing to form a hard film. A mask of photo-resists having a series of slots corresponding to the required sets of second signal conductors 10 is positioned over the polyimide film and stripes of aluminium or chromium followed by gold are then vacuum deposited after which the photoresist mask is removed. The polyimide film is then selectively etched away leaving the second set of conductors 10 insulated from the first conductor 8 by the remaining portions 9 of the polyimide film. Various circuit arrangements are produced by cutting the conductors 8, 10 by a spark machining operation, electron or laser beam scanning, etching, scribing on using a condenser discharge. Connections between conductor sections are made by conducting links 15, 16 deposited by a photo resist and vacuum deposition method. The chips 2 may be inserted in the apertures 5 either before or after the conductors 8, 10.

Abstract: 1,206,308. Semi-conductor wafer; image pick-up tubes. SONY CORP. 21 Nov., 1968 [22 Nov., 1967], No. 55206/68. Headings H1D and H1K. To avoid cracking during processing a thin single crystal semi-conductor wafer is provided with an integral peripheral portion of polycrystalline material. This is achieved by forming on a marginal portion of a surface 1a of a single crystal substrate 1, e.g. of N-type Si, a site which is crystallographically different from the rest of the surface, e.g. by thermal decomposition or oxidation or by vapour deposition of silicon oxide 2. A layer 4 of N-type Si is then vapour deposited on the surface 1a, forming as polycrystalline material 4B over the marginal portion 2 but as single crystal material 4A over the exposed substrate surface. The substrate is subsequently removed, e.g. by cutting and grinding, to leave only the unsupported layer. If the substrate 1 contains a high impurity concentration the impurity concentration of the single crystal portion 4A will increase towards the substrate due to diffusion during deposition. This is of particular value when the invention is applied to the target of a vidicon tube. which comprises an array of diodes formed by diffusion of an array of spaced P-type zones into the single crystal portion 4A prior to removal of the substrate. Spaced transistors may alternatively be formed by diffusion into the single crystal portion 4A, and after removal of the substrate individual devices may be obtained by dicing the single crystal portion 4A. An integrated circuit is also described in which individual components are formed in regions (4A 1 , 4A 2 , 4A 3 ), Fig. 6 (not shown), of the single crystal portion (4A) spaced from one another by polycrystalline regions (4B<SP>1</SP>) additional to the peripheral polycrystalline portion (4B). After application of the necessary interconnections between components the substrate is removed and the polycrystalline regions (4B<SP>1</SP>) are selectively etched away, leaving the components mutually isolated by air-gaps.
