Semiconductor measurement technology: A versatile high-voltage bias supply for extended range MIS C(V) and G(V) measurements
Abstract
A versatile high-voltage power supply intended for use as a bias source in carrying out such measurements is described. The design allows the user a wide variety of options in the selection of the sweep function (waveform), sweep time, initial bias voltage, and the amplitude of the bias sweep. There are six possible sweep functions: (1) increasing ramp, (2) decreasing ramp, (3) positive polarity half-wave sawtooth (increasing ramp followed by decreasing ramp), (4) negative polarity halfwave sawtooth (decreasing ramp followed by increasing ramp), (5) full-wave sawtooth starting with increasing ramp, and (6) full-wave sawtooth starting with decreasing ramp.
