Abstract

1,216,005. Semi-conductor transducers. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 7 March, 1968 [13 March, 1967], No. 11275/68. Heading H4J. [Also in Division H1] A surface region 2 of a semi-conductor body 1 forming an electromechanical transducer (e.g. a microphone or pick-up) is doped with deep level impurities and provided with a metal layer 4 forming a rectifying contact 5 with the region 2. In the embodiment the body 1 is of N-type Si, but Ge and GaAs are also referred to. The deep level impurities in the region 2 may be Cu, Fe, Ni, Au, Co, Mn, Cd and/or Zn. The metal layer 4 may be evaporated, plated or sputtered and may comprise Mo, W, Pt, Au, Ag or Al. A non- rectifying electrode 3 applied to the body 1 comprises Au/Sb alloy.
