Abstract

980,513. Semi-conductor devices. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Nov. 17, 1961, No. 41266/61. Heading H1K. A silicon body to which material is subsequently alloyed to form a PN junction is prepared by etching in a solution containing nitric and hydrofluoric acids, to which before or during etching, alkali or alkaline earth metal ions are added. In a typical process silicon discs are etched to within 40Á of the required thickness in a solution of 2-4 volumes nitric, 4-2 volumes hydrofluoric and 6 volumes acetic acid of specified concentration and rinsed in deionized water. After etching to the desired thickness in a fresh solution of the acids a 10% by weight solution of an alkali or alkaline earth salt is added to form between 2 and 10% of the solution and etching continued for two minutes while the solution is agitated. The discs are then rinsed in deionized water and stored in alcohol until the alloying process. Suitable salt solutions are the chlorides, nitrates or carbonates of magnesium, calcium, barium and strontium. The method is said to be particularly suited to the production of rectifiers, transistors and photo-cells.
