ELECTRO-ULTRASONIC SPECTROSCOPY OF MOSFETS

Original language description

We have tested the sample of MOSFET by electro-ultrasonic spectroscopy. Electro-ultrasonic spectroscopy is non-destructive testing method. This method is based on interaction of two signals. Electrical signal of frequency fE and ultrasonic signal of frequency fU. The ultrasonic signal induces the resistance change in the sample structure. Defects and un-homogeneities are the sources of new signal on frequency which is given by superposition or subtraction of exciting frequencies fE and fU. We suppose that the ultrasonic wave have some influence on the particle mobility. We have tested the sample of MOSFET IRF 510. We have analyzed signal on frequency of ultrasonic excitation fU for different amplitudes on DC drain voltage and gate voltage. In this paper you can see some results which consequent from our measurements
