Abstract
PURPOSE: To produce a high-reliability device with a sure soldering and no insulation deterioration by subjecting only the soldering part of a chip to silver plating which gets wet well with a high-temperature solder.
CONSTITUTION: The metal part surface of TO-5 type base 5 is subjected to silver plating 15, and further,only soldering part 6 of the semiconductor chip is provided with silver plating 16 which gets wet well with a high-temperature solder. By this constitution, the soldering of the chip is ensured; and since the phenomenon of silver moving to the glass insulating material is not generated because of no silver plating in the metallic part contacting with glass insulating material 13, so that deterioration or short-circuit can be prevented
