Query: The influence of edge effects on the determination of the doping profile
  of silicon pad diodes   Edge effects for square p+n pad diodes with guard rings, fabricated on
high-ohmic silicon, are investigated. Using capacitance-voltage measurements of
two pad diodes with different areas, the planar and the edge contributions to
the diode capacitance are determined separately. It is shown that the doping
concentration derived from the capacitance-voltage measurements with and
without edge corrections differ significantly. After the edge correction, the
bulk doping of the pad diodes is found to be uniform within +/- 1.5%. The
voltage dependence of the edge capacitance is compared to the predictions of
two simple models.
