Resistivity Meters
Periodic compliance checks of ESD work surfaces are super important. Monitors only verify the ground plane, or path to ground. The surface itself can wear down, become dirty, or if you use low quality mat—just not hold up. A handheld Surface Meter is great for running monthly, or prescriptive compliance verification of your ESD surfaces.

Software
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.
