| 摘要 |
The invention relates to semi-conductor amplifiers, and the manufacture includes a process in which an electrode is fixed to the semi-conductor body by means of a solder comprising 63 per cent. tin and 37 per cent. lead, or 5-10 per cent. antimony and 95-90 per cent. tin. The antimony diffuses into the semi-conductor body, which may be germanium or silicon, to change its electrical characteristics. Reference is made to the use of gallium instead of antimony. |
