10Hz-1MHz Semiconductor Device C-V Testing System

      Capacitance-Voltage (C-V) Measurement is widely used to characterize semiconductor parameters, particularly in MOS capacitors (MOS CAPs) and MOSFET structures. The capacitance of a metal-oxide-semiconductor (MOS) structure is a function of the applied voltage. The curve depicting capacitance variation with voltage is termed the C-V curve (or C-V characteristics). This measurement enables precise determination of critical parameters, including:

· Oxide layer thickness (dox)

· Substrate doping concentration (Nn)

· Mobile charge density in the oxide (Q1)

· Fixed oxide charge density (Qfc).
