Title: Improvements in or relating to the production of semi-conductor devices
IPC: H01L21/228
Filed: 1960-08-05
Abstract: 950,467. Semi-conductor devices. SIEMENS & HALSKE A.G. Aug. 5, 1960 [Aug. 6, 1959], No. 27203/60. Heading H1K. In making a PN junction by the normal alloying technique heating is continued after solidliquid equilibrium is reached for 6-7 times as long as it took to reach equilibrium to enable impurity diffusion to produce a shallow PN junction. In the example indium emitter and collector pellets are applied to opposite faces of an arsenic doped N-type germanium body and alloyed thereto by heating to 500-600 C. for 1 hour. Heating is then continued for a further 6-7 hours at the same or at a lower temperature. This results in a collector junction of increased breakdown voltage and reduced capacitance. A drift transistor may be produced by incorporating arsenic into the emitter pellet to produce the required impurity gradient in the base zone. Alternatively such a gradient may be obtained by producing the collector junction by the above alloy-diffusion technique and the emitter by the normal alloying process.

The work is advanced by rollers 4, 5 journalled in a triangular frame 6 for rocking motion about its apex where it is secured to an arm 7, the latter being acted upon by an adjustable spring 20, through the shaft 24 and arm 7a. The latter arm is engaged by a cam 13 which is adjustable by lever 8 to set the minimum clearance between the rollers and saw blades. A flat 13a on the cam gives a self locking action when the arm 7 is fully raised for attention to the saws &c. Lever 27a is provided to give an independent lifting action on the rollers and is controlled by the pedal 26. It is attached to the triangular plate by a slotted connection to allow the rollers to adjust themselves to slight irregularities in the work size and is attached nearer the roller 4 so that this roller exerts more pressure on the work than the other roller 5. Idling rollers 28, 29 facilitate movement of the work. The rollers are driven by a chain engaging sprockets 4a, 5a, 16 and idler 17 and a further chain engaging sprockets 16 and 19. The latter is driven from an independent motor through a gearbox. The sawblade unit may be removable or adjustable in height.
