Ultra Sound Imaging for Nanoelectronics

Technology Inceptions

Researchers at TU Delft University have developed a proof-ofconcept method to use ultrasound imaging in nanoelectronics as existing optical and electron microscopy are not accurate enough or applicable to deeper structures. The new method uses the same principle as ultrasound scanning in pregnancies, but on a much, much smaller scale. The method is particularly interesting in nanoelectronics as it enables placing two layers on top of each other with nanometre precision. Outside of electronics, it could be use in cell biology to make a detailed 3D image of a single living cell. For eg of the way mitochondria are folded in a cell. And in materials science, it could be used for research into heat transport in an amazing material such as graphene. Increasing miniaturization of electrical components has motivated researchers to look for better imaging options.
