Abstract
1,040,990. Semi-conductor devices. GENERAL ELECTRIC CO. April 15, 1964 [May 10, 1963], No. 15671/64. Heading H1K. Transistors are manufactured by mounting a plurality of semi-conductor pellets 2, each having a plurality of electrically active regions defining at least one PN junction, at intervals along an elongated metallic carrier 20 by means of an electrically conductive bond (such as a layer of gold solder 22) between the carrier 20 and one active region of each pellet 2, securing lead wires 26, 28 to the remaining active regions of each pellet 2, attaching a segment of the carrier 20 bearing one of the pellets to one lead post 34 of a header assembly 30, attaching the lead wires 26, 28 of this one pellet to other lead posts 32, 36 of the header assembly, and enclosing the pellet, leads, lead posts, and carrier segment in a housing (such as an epoxy resin encapsulant 50, with one flat face 52 as an orientation indicator). As shown, the segment of the carrier 20 bearing the end pellet is secured by a weld 42 to the lead post 34 and is then sheared off from the rest of the carrier at 44, the carrier 20 with pellets and lead wires attached having previously been thermally stabilized at about 300 C. for several hours.
