Title: Improvements in or relating to methods of manufacturing transistors
IPC: H01L21/228
Filed: 1961-01-27
Abstract: 958,521. Transistors. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 27, 1961 [Jan. 30, 1960], No. 3258/61. Heading H1K. In a transistor, at least a portion of the base zone is provided by diffusing during the alloying of the emitter, an impurity to convert a region of the body of one conductivity type to the opposite type, the contact material used for the alloy-diffusing process being free of the lifetime reducing impurity which initially exists throughout the body. The concentration of the lifetime reducing material is thus reduced in that portion of the base zone lying between the emitter and the collector. Fig. 3 shows a P-type gold-doped germanium wafer 3 to which a first pellet 5 containing lead with 5% antimony and 1% aluminium and a second pellet 6 of lead with 5% aluminium have been fused. Heating for 6 minutes at 750‹ C. provides an N-type base layer 4 due to diffusion of the antimony and recrystallized layers 7 of N-type material and 8 of P-type containing aluminium. During the process gold from the body diffuses into the contacts leaving the base zone 4 with reduced concentration of gold. Other lifetime reducing impurities such as nickel, iron or copper may be used, and silicon may be used instead of germanium. Indium, gallium and arsenic may be used as impurities for the alloying and diffusing process. A masking lacquer layer may be provided between base and emitter contacts 5 and 6 and the remaining semi-conductor surface then etched away to provide a transistor as shown in Fig. 4.

A valve for use, e.g. in the stack-pipe of an atomic reactor which automatically closes to prevent the escape of dangerous gases on the removal of a hollow casing 16, Fig. 1, housing a winch by which fuel rods and other parts may be raised from or lowered into the reactor, comprises a valve plate 21 carried on an arm 22 keyed to a spindle 23, Fig. 3, for angular movement toward and away from a seat ring 13 connected to the upper end of a deformable bellows 17 which is connected to the stack 10 by a ring 18. The seat ring 13 after removal of the casing is normally covered by a cover-plate (not shown). Tie rods 19 surrounding the bellows limit extension of the bellows due to gas pressure within the stack. The spindle 23 has keyed thereto a pinion 25, meshing with gear teeth on a member 26 freely mounted on a spindle 27 parallel with the spindle 23. The spindle 27 has secured thereto a sleeve member 28 having a flange 29 formed with dogs 31 engageable in arcuate recesses in the member 26 and webs 33 through which passes a pin attached to the upper end of a spring-loaded rod 41. The rod 41 enters a tube 42, Fig. 2, anchored at its lower end to the ring 18 and is urged downwardly by the engagement between a head 43 on the rod and spring-loaded arms 44 on a predetermined expansion of the bellows brought about by the removal of the casing 16 and associated winch, to release a latch lever 38, Fig. 4, also carried by the webs 33 from engagement with a nose 36 on a member 34 freely mounted on the sleeve member 28. Spiral springs 32 anchored to the spindle 27 and to a fixed bracket 24 then rotate the spindle 27 and through the engagement of the dogs 31 in the arcuate recesses and the gear teeth, the spindle 23 to close the valve. To open the valve when the casing 16 and winch are mounted on the seat ring, a plunger 55 having a rod passing sealingly through the seat ring is moved downwardly on rotation of a hand wheel to rotate the arm 34 and through the latch lever 38 the sleeve member 28 to further tension the springs 32. The dogs 31 then being in contact with the arcuate recesses so that the valve plate opens under its own weight. To re-engage the latch lever 38 with the nose 36, the plunger 55 is retracted upwardly whence a spring (not shown) anchored to the members 34, 28 causes the member 34 to follow the movement of the plunger 55. The valve may be closed manually by rotating the plunger 55 upwardly so that the loading of the springs 32 is transmitted to the valve plate 21 through the dogs 31. The valve may also be closed independently of the springs 32, by downward movement of a plunger 54 similar to the plunger 55, which through a rocker arm 48 freely mounted on the spindle 27 and connected to a crank-arm 45 secured to the spindle 23 rotates this latter spindle to close the valve.
