Junction Measurement and Analysis
Materials Development Corporation
A comprehensive set of analyses for junction diode or Schottky barriers begins with C-V data gathering that adjusts the voltage step to the slope of the C-V characteristics. This assures an optimum set of C-Vdata whether the voltage range is small or large. Doping profile and resistivity profile are both available at the touch of a key. Plots of 1/C2 - V or Log(C) - Log (V+ phi) show doping uniformity and doping slope factor. Exclusive recalculation options allow adjustment of stray capacitance and area to facilitate calibration using a standard reference wafer of known doping or resistivity.
