Abstract
768,740. Semiconductor devices. HUGHES AIRCRAFT CO. Nov. 8, 1954, No. 32309/54. Addition to 721,201. Class 37. A semiconductor diode comprises a vitreous envelope consisting of a tubular body section 28 (Fig. 5) and end sections 14 and 54. Ductile lead wires 12 and 50 are sealed to and extend through the end sections, one wire bearing a resilient electrode 48 and the other a semiconductor element 16. The maximum diameter or cross-section dimension of the diode is one-tenth of an inch, the length of the seal between each wire and end section is at least 1.5 times, and the diameter of each end section is at least five times, the diameter of the associated wire. The device may be produced, as shown in Fig. 4, by first sealing glass beads 14 and 54 to "Dumet" wires 12 and 50, and then sealing bead 14 to glass tube 28. A germanium or silicon wafer 16 which has silver and copper, or antimony and gold platings is then fixed to the end of wire 12 by a paste of silver or gold dispersed in a thermosetting resin which is baked. Whisker 48 is spot welded to wire 50, and then bead 54 is sealed to the other end of tube 28. As compared with the parent Specification, the present invention strengthens the end-seals, and avoids the need for annealing and etching the semiconductor surface during manufacture.
