Abstract
1,244,759. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MFRS. Ltd. 11 Dec., 1968, No. 58828/68. Heading H1K. A method of interconnecting two devices T 1 and T 2 , in an integrated circuit, which are mutually isolated by a groove 6, comprises providing a conductive metal bridge 19 over the groove. The steps of forming the bridge comprise providing a plug of material at the surface of the semi-conductor body between the two devices T 1 and T 2 , forming a conductive metal layer between the electrodes 15 and 33 of the two devices, removing the plug by etching so that the surface of the semi-conductor body underlying the conductive metal layer is exposed, and etching a groove 6 into the semi-conductor body to isolate the two devices. An insulating layer of silicon oxide, silicon nitride, silicon carbide or aluminium oxide is provided on the surface of the semi-conductor body which may be of silicon, germanium or gallium arsenide, and serves as a mask during processing. The plug is of aluminium and is removed by etching with hot sulphuric acid. The electrodes 12, 13, 15, 32, 33 and 35 are of aluminium coated with titanium which itself is coated with gold, the gold layer later being thickened by electroplating. The plug may alternatively be of copper and the interconnections of molybdenum, nickel, platinum or silver. After the removal of the plug, the groove 6 is formed by etching the semi-conductor body with hydrazine and water in equal molecular ratio, the body having been so arranged that the groove orientation is parallel to the intersection of the <111> crystal planes with the body surface parallel to the <100> crystal plane so that the etching wil result in a groove of V-shape cross-section.
