Paper Abstract

We demonstrate the use of an infrared focal plane array (IR-FPA) to measure the spatially resolved surface temperature of a GaAs MESFET (gallium arsenide metal-semiconductor field-effect transistor) under dc and rf operating conditions. By compensating for variations of the small emissivity, absolute temperatures of plus or minus 5 degrees Celsius, and small temperature differences of 1 degree Celsius can be determined. By deconvolution of the lens MTF (modulation transfer function) we attain a resolution of 6.25 micrometer. The combination of thermal and spatial sensitivity makes our set-up ideally suited for non- destructive characterization of semiconductor devices.
