Detecting hidden nanostructures by converting light into sound

from Advanced Research Center for Nanolithography via Phys.org

Detecting hidden nanostructures by converting light into sound Advanced Research Center for Nanolithography via Phys.org Researchers at ARCNL have found a way to detect nanostructures buried under many layers of opaque material using high-frequency sound waves induced by light. Their findings could have applications in the semiconductor manufacturing industry, such as wafer alignment. The researchers also revealed interesting new phenomena in photo-acoustics that have not been investigated before. READ MORE
