Latest Patents
One of Altmann's latest patents is titled "Three-dimensional hot spot localization." This invention presents a non-destructive approach for the 3D localization of buried hot spots in electronic device architectures using Lock-in Thermography (LIT). The analysis is grounded in the principles of thermal wave propagation through various material layers, which results in phase shifts and thermal time delays. As electronic devices become more complex with multi-level stacked die architectures, it is essential to acquire multiple LIT results at different excitation frequencies for accurate hot spot depth localization. Furthermore, the use of multiple time-resolved thermal waveforms, measured in a minimized field of view directly above the hot spot location, can expedite data acquisition. The shape of these waveforms can be analyzed to enhance detection accuracy and confidence levels.
