Abstract

1,179,062. Semi-conductor devices. TRANSISTOR A.G. 23 June, 1967 [8 July, 1966], No. 29054/67. Heading H1K. The source of a dopant to be diffused into a semi-conductor wafer is a glass layer formed thereon and including a compound of the dopant. After diffusion the glass layer is removed and electrodes are applied. The Specification describes the manufacture of a Si diode or transistor, a P-containing glass layer being formed on the wafer surface by spreading a solution of P 2 O 5 in alcohol or methyl glycol and heating to 1200‹ C. Alternatively a nitride of the dopant may be used, or the glass layer may be evaporated on to the wafer. The glass coating everywhere but on the diffusion area is then etched away using conventional masking or photo-resist methods, and the diffusion is carried out in an oxidizing atmosphere, which produces an oxide coating on the exposed surface. After removal of this oxide and the remaining glass layer, electrodes and a protective coating of oxide or lacquer are applied. To produce a transistor the process is repeated using B as the dopant.
