Abstract: 1,024,210. Semi-conductor devices. ASSOCIATED SEMICONDUCTOR MANUFACTURERS Ltd. Feb. 26, 1965, No. 8380/65. Heading H1K. In the manufacture of a semi-conductor device the envelopeis produced by assembling a ceramic tube 1 between two hollow metal bushes 2, 3 on an electrically conductive rod (not shown). Rings of brazing material are, placed between each end-surface of the tube and the bush to which it is to be joined. A current is passed through the rod to raise the temperature of the assembly and braze the tube to the bushes. During the process the components are held under a slight pressure and are placed in an argon atmosphere. With a suitable choice of materials metallizing of the tube is not needed. For example, the bodies may be of titanium or zirconium, the ceramic tube of alumina, and the brazing rings of copper or of a copper-silver alloy. The device shown is a microwave diode. After the formation of the envelope a nickel support 5 to which is soldered a titanium cat's whisker 9 is inserted into the titanium bush 3, and a nickel support 4 to which is soldered a germanium wafer 8 of 2-10 x 10<SP>-3</SP>ohm/cms. resistivity is inserted into the other titanium bush. The supports are made tight fits with the bushes. When the parts are correctly positioned titanium end pieces 6, 7 are inserted and brazed to the bushes at points remote from the ceramic tube.
