Electrical parameters:

  1. Characterization of starting wafer: P or N
  2. Resistivity: For measurement of hole and electron concentration
  3. Carrier mobility

Four Probe method:

enter image description here

It is a common method to measure resistivity. In this method basically the current flowing for the unknown applied voltage is measured to calculate resistance or vice versa. …
