Title: Method of and apparatus for discriminating p-type and n-type of semiconductor
Inventor: TAKAHASHI RIYOUICHI
IPC: H01L21/66
Filed: 1978-12-07
Abstract: PURPOSE: To ensure accurate discrimination regardless of contact condition of the electrode by detecting the polarity of the charge yieled by irradiation of light with three needle-like electrodes touching on the semiconductor in such a manner that a constant current flows through two of the electrodes from the power source with one electrode connected to the detector.  
     CONSTITUTION: Needle-like electrodes 10W20 made of tungsten carbide about 0.5mm in diameter with a sharp tip are arranged to touch on a semiconductor 13 intended to discriminate the conductivity type and a constant current flows through two of the needle electrodes from the constant current source 14. One thereof is connected to one terminal of a detector 16 by way of a lead wire 18 and one free terminal of the two electrodes 10 and 12 are connected to the other terminal of the detector 16 by way of a selection switch 17 and a lead wires 19 and 20. In such an arrangement, when a light pulse is irradiated on the back of the semiconductor 13 from a light pulse generator 15, the charge produced between the electrodes 10 and 12 is positive if the semiconductor is a P-type while negative if it is an n-type. Thus, the conductivity type of semiconductors can be discriminated easily by detecting the polarity thereof with a detector.
