Title: Junction switching transistor and method for its manufacture
IPC: H01L27/07
Filed: 1960-07-18
Abstract: 955,997. Transistors. RAULAND CORPORATION. July 18, 1960 [July 16, 1959], No. 24932/60. Heading H1K. A switching transistor comprises a semiconductor wafer having emitter and collector regions and a further rectifying contact to the base zone spaced at a distance exceeding the diffusion length; the collector region is produced by alloying and diffusing both acceptor and donor materials to provide a low resistivity region of base conductivity type under the collector region. Fig. 1 shows the transistor consisting of a wafer 3 of N-type germanium with emitter 2 and collector 9 rectifying contacts and a rectifying contact 5 to the base zone. The emitter and base contacts are connected to nickel leads 6 which are sealed into glass beads in base member 11 of steel or copper. The nickel collector lead 9 is screwed into a raised portion 10 of base 11 which acts as a heat sink. The emitter PN junction 2 and base PN junction 5 are both provided by alloying a pellet consisting of 99.5% indium and 0.5% gallium by weight to the N- type wafer. The collector PN junction is provided by alloying a mixture of donor and acceptor materials such as a one to one atomic ratio of antimony and gallium in a carrier material such as indium, the antimony and gallium constituting 5% of the whole; the process provides a diffused N+ region under a recrystallized P- type region. The alloying process may be carried out by first fusing a pellet of the impurity material to the end of a nickel wire in a jig and then placing the wire in a hole 17 in one portion of a carbon jig (Fig. 4) so that it is positioned against the surface of a semiconductor wafer 3 in a recess in the second portion 21 of the jig. After alloying the emitter, the wafer is reversed so that the wire lies in hole 22 and the collector 9 is alloyed in the same manner. The PN junction is formed at the same time as the collector by alloying pellet 27 (Fig. 5D) on wire 12 in hole 18. The assembly is sealed in a metal or glass cover in a nitrogen or other inert atmosphere. The process provides a device having a negative resistance portion between high and low resistance regions in the collector currentcollector voltage characteristic so that it can act as a switch; the breakdown or switching voltage is variable according to the value of the forward biasing current supplied through the base junction electrode. Fig. 8 shows a circuit with means for controlling the bias to base electrode 5 to control the current from A.C. source 32 through load R 2  which may be the field coils of a D.C. motor. Specification 909,495 is referred to.
