842,366. Semi-conductor devices &c. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 26, 1956 [Sept. 29, 1955], No. 29393/56. Class 37. In a semi-conductor device, at least the part adjacent the electrode of a current supply wire comprises at least 5 % of chromium and at least 5% of nickel, to render it etch resistant, the Figure shows an N-type germanium crystal 1 soldered by a tin-antimony solder to a giltmolybdenum plate 3 and an indium alloy electrode 3 having a supply wire 5 consisting of 20% chromium and 80% nickel. The supply wire is resistant to etching solutions such as a solution of hydrogen peroxide and hydrofluoric acid, and a solution of nitric, hydrofluoric and acetic acids and bromine. |
