1,138,401. Joining glass and metal. P. R. MALLORY & CO., Inc. 22 April, 1966 [6 May, 1965; 6 Dec., 1965], No. 17792/66. Heading C1M. [Also in Divisions B3, C7 and H1] An electrically conductive or semi-conductive material is joined to an insulating material (glass, quartz, sapphire) by forming an electrolytic interface layer of oxide, the joining being conducted at a temperature sufficiently high to render the non-conductive material electrically conducting but not sufficiently high to melt either component. The components are solid state electronic devices (see Division H1). Particular conductive or semi-conductive materials referred to are: silicon, aluminium, germanium, gallium arsenide, platinum, beryllium, titanium and palladium. |
