Abstract: 1520474 Semiconductor device manufacture PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 15 Sept 1975 [18 Sept 1974] 37864/75 Heading H1K A conductive pattern is provided on a semiconductor wafer and/or layers thereon by first forming an auxiliary layer with apertures corresponding to the required pattern and consisting of a metal coated with a layer of anodic oxide, depositing conductive material overall and then removing those portions overlying the auxiliary layer by selective etching of the metal or oxide thereof. In the described embodiment (Fig. 4) the conductive pattern, 0À8 Á thick, which contacts a diffused zone 5 in an oxide coated silicon wafer 2, consists of titanium, rhodium and gold sub-layers sequentially applied by vapour deposition or cathodic sputtering. The auxiliary layer 6, 8 of anodized aluminium is formed by vapour depositing aluminium overall to a thickness of 1Á, applying a photoresist mask corresponding to the required pattern, anodizing the unmasked areas to a depth of 0À07 Á, in tartaric acid or ammonium tartrate, removing the mask and completely etching away the exposed aluminium with slight undercutting of the oxide film. With wafers of silicon, gallium arsenide and gallium phosphide an auxiliary layer of aluminium is preferred but titanium is more suitable on wafers of gallium aluminium arsenide. Alternative layer materials are zirconium and tantalum. The conductive pattern may alternatively consist of a lower layer of titanium, chromium, zirconium, cobalt, tungsten or tantalum, an intermediate layer of rhodium and upper layer of rhodium, platinum or palladium. Suitable etchants for aluminium and titanium are specified. Reference has been directed by the Comptroller to Specification 1,435,320.
