Abstract

742,239. Semiconductor devices. ASSOCIATED ELECTRICAL INDUSTRIES, Ltd. Oct. 23, 1952 [Oct. 24, 1951], No. 8345/55. Divided out of 742,172. Class 37. A sharply defined PN junction is produced by electrolytically depositing a thin film of semiconductor material such as germanium of one conductivity type on to a piece of semiconductor material of the opposite conductivity type. The Provisional Specification also describes other methods of providing PN junctions, as described in Specification 742,172.
