Abstract

1504035 Semi-conductor devices SIEMENS AG 29 April 1975 [1 July 1974] 17880/75 Heading H1K In a thyristor having an auxiliary emitter region 5 between the main emitter region 1 and the control electrode 8 the thickness of the main emitter electrode 6 is greater than that of the auxiliary emitter electrode 7 so that the flat surface of a contact electrode 9 supported on the main emitter electrode 6 and projecting over the auxiliary emitter electrode 7 is spaced from the latter. Three photo-etching methods of achieving this result are described.
