Probe for determining p or n-type conductivity of semiconductor material |
| abstract |
A probe for determining the p or n-type of semiconductor material wherein a conductive wire is positioned for point contact with the semiconductor, forming a diode. The wire is energized by r.f. current passing through a capacitor so that the current is rectified at the diode, charging the capacitor. A voltage comparator is connected to the capacitor for determining the polarity of charge on the capacitor and hence the p or n-type of the semiconductor wafer. The semiconductor is supported on a non-diffusing dielectric over a conductive carrier such that r.f. current passes through the dielectric to the carrier, thereby completing the circuit. |
