Characterization of punch-through phenomenon in SiC-SBD by capacitance-voltage measurement at high reverse bias voltage

This paper investigates the punch-through phenomenon in SiC Schottky Barrier Diodes (SBD) from capacitance–voltage (C–V) characteristics at high reverse bias voltage. High voltage bias application has not been possible by conventional measurement instrumentation. The authors, therefore, develop C–V characteristics measurement instrumentation which enables the application of high dc bias voltage...

Evaluation of capacitance-voltage characteristics for high voltage SiC-JFET

Capacitance between terminals of a power semiconductor device substantially affects on its switching operation. This paper presents a capacitance–voltage (C–V) characterization system for measuring high voltage SiC–JFET and the results. The C–V characterization system enables one to impose high drain-source voltage to the device and extracts the capacitance between two of three terminals in FET...

Characterization of Contact Electromechanics through Capacitance-Voltage Measurements and Simulations

Electrostatically actuated polysilicon beams fabricated in the MUMPs process are studied, with an emphasis on the behavior when the beam is in contact with an underlying silicon nitride dielectric layer. Detailed 2D electromechanical simulations, including the mechanical effects of stepups, stress-stiffening and contact, as well as the electrical effects of fringing fields and finite beam thick...

SiC High Blocking Voltage Transistor

Recently, energy saving is strongly required to prevent global warming.
