Abstract

1,044,606. Capacitors. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 30, 1965 [June 30, 1964], No. 27643/65. Heading H1M. In the manufacture of the multi-layer capacitor shown, a layer 11 and two relatively small masses 12 and 13 of anodisable metal, e.g. tantalum, niobium, zirconium, titanium, hafnium and aluminium are deposited by cathodic sputtering on a glass or other refractory substrate 14. An oxide layer 15 is formed on layer 11 by anodising, masses 12 and 13 being masked. Counter-electrode 16, of nickel, gold, silver, tin, lead or copper, is applied by vapour deposition to the oxide layer and covers now unmasked portions of the masses 12 and 13. An insulating covering 17 of e.g. silicon monoxide or dioxide is vapour deposited on to layer 16 and portions of masses 12 and 13. When a second layer 18 of anodisable metal, deposited on layer 17 by cathodic sputtering, is subjected to anodising to form oxide layer 19, the anodization voltage which otherwise might have led to breakdown of the first dielectric layer, now results in the formation of oxide layers 20 and 21 on the exposed surfaces of masses 12 and 13. Conductive films 23 and 24 are deposited by cathodic sputtering to penetrate films 20 and 21 and make electrical contact with masses 12 and 13, thereby connecting electrode 16 to subsequently vacuum deposited electrode 22. Finally second insulating covering 25 is applied.
