PURPOSE:To enable the correction of an inverted semiconductor pellet through magnetic field, by making one electrode of the pellet of a magnetic substance layer before a glass tube containing the pellet is put in a sealing jig and heated so that the tube and the pellet are integrated with each other. CONSTITUTION:A bump electrode 7 of Ag is provided on one of the obverse and reverse sides of a semiconductor pellet 5 and an electrode 8 is provided on the other side. The electrode 8 is made of a magnetic laminated layer of Cr, Ni and Ag. Lead members 3, 4 for a heat sink, which have slug leads 1, 2, are inserted into a glass tube 6. The tube is then put in a housing section 16 provided in a sealing jig 17 of graphite or the like. The jig 17 is electrically heated so that a projection 9 for holding the pellet 5 down is made on the inside surface of the tube 6 and the pellet and the tube are integrated with each other. An electromagnet 19 is provided on the lead 1 projecting from the jig 17. If the pellet 5 is inverted, it is set upright by the magnetic field of the electromagnet 19. |
