Abstract

PURPOSE:To obtain a double heat sink type glass-sealed diode having high productivity by alternately continuing lead wires functioning also as radiators and diode pellets, inserting them into a glass bulb and cutting the bulb at the prescribed interval while exposing the lead wire structure at both ends. CONSTITUTION:A plurality of double lead wires 17 formed with dividing grooves 16 at the respective side centers are arranged on a rectilinear line by using an assembling jig 13 while spacing at an infinitesimal gap 18 therebetween, semiconductor pellets 1 formed with bumps 2 on a P<+> type layer in P<+>-N-N<+> configuration are disposed within the gap 18, as a holding structure 19. This structure 19 is transferred into a lead glass hulb 20 having an inner diameter slightly larger than the outer diameter of the wire 17 by using the jig 13, many such bulbs 20 are aligned and loaded into an electric furnace, are thus heated while evacuating the bulbs to melt and seal the wire 17 with the bulb 20. Thereafter, the bulbs 20 are removed from the furnace, the bulbs 20 are cut at the grooves 16 as a mark, and sealed diodes are respectively formed.
