Making Optimal Capacitance and AC Impedance Measurements with the 4210-CVU Capacitance Voltage Unit––APPLICATION NOTE
■Capacitance-voltage (C-V) and AC impedance measurements are commonly performed on many types of devices for a wide variety of applications. For example, C-V measurements are used to determine these device parameters:
▲Gate oxide capacitance of MOSCAPs
▲MOSFET input and output capacitance
▲Built-in potential of solar cell
▲Majority carrier concentration of a diode
▲Capacitance between terminals of a BJT
▲Oxide thickness, doping density, and threshold voltage from a MIS capacitor
■The 4210-CVU is a multi-frequency (1 kHz to 10 MHz) AC impedance measurement module for the 4200A-SCS Parameter Analyzer (see Figure 1) that enables the user to make C-V measurements easily. The CVU is designed with unique circuitry and is controlled by the Clarius software to support features and diagnostic tools that ensure the most accurate results. Some of the 4210-CVU’s built-in tools include real-time measurement mode, open/short compensation, parameter extraction formulator, filtering, timing controls, and the ability to switch the AC ammeter terminal in the software. These tools, along with using proper cabling and C-V measurement techniques, allow the user to make highly sensitive capacitance measurements.
■This application note describes how to make optimal capacitance measurements using proper measurement techniques and the 4210-CVU Capacitance Voltage Unit.
