Abstract
PURPOSE: To prevent solder from creeping on a semiconductor device without surface treatment on the side surface of a metallic disk for absorbing thermal expansion difference.
CONSTITUTION: Gold 11 is superimposed on only the upper and lower surfaces of molybdenum disk 9 of base nickel 10. This disk 9 is soldered at 12 to a dischrge plate 8, and secured to a semiconductor 7 with gold and silicon eutectic solder 13. According to this configuration, molybdenum is exposed on the side surface of the disk 9 to be improperly wettable with solder 12 to thereby prevent the solder 12 from creeping onto the disk 9. Accordingly, it can readily and exactly adhere with high reliability.
