Abstract

1,008,807. Semi-conductor devices. MULLARD Ltd. June 14, 1963 [Oct. 15, 1962], No. 38916/62. Drawings to Specification. Heading H1K. In a method of applying an ohmic contact to a semi-conductor body, the surface area to which the contact is not to be applied is covered with a resist layer, such as a lacquer sprayed on while the semi-conductor body is held in clamps which cover the area to which the contact is to be applied, and this area to which the contact is to be applied is then dipped for a short time into a bath of liquid solder. The solder bath may contain a flux and may be ultrasonically agitated, and the atmosphere above it may be provided by a current of argon or other inert gas.
