Abstract
A method for providing a high spatial resolution thermal imaging of an active electronic device. The method includes placing an electronic device on a testing stage of an imaging system. The method, calibrating the imaging system by determining thermoreflectance coefficient for a plurality of pixels forming thermal images, each pixel having a coordinate (x,y) captured from the electronic device at each of a plurality of wavelengths of illumination (C(x,y,λ), activating the electronic device, and determining changes in reflection for each of the plurality of pixels at each of the plurality of wavelengths (ΔR/R), determining ΔR/R vs. C(x,y,λ) for each of the plurality of pixels for each of the plurality of wavelengths, fitting ΔR/R vs. C(x,y,λ) to a predetermined mathematical function and use the parameters to calculate the temperature at each pixel.
