Attolight

About

Attolight AG is a Swiss company founded in 2008, focused on developing cathodoluminescence (CL) tools for defect inspection and materials characterization in the semiconductor industry, research labs, and academia. Based at the EPFL Innovation Park in Ecublens, Switzerland, Attolight has a global presence with installations across Europe, Asia, and North America, along with a subsidiary in Cambridge, MA. The company specializes in quantitative cathodoluminescence (q-CL), which integrates electron and light microscopy for non-destructive, nanoscale analysis. This technology allows for the detection of ultra-trace impurities and defects with high spatial resolution. Attolight offers integrated CL systems, add-ons for transmission electron microscopy (TEM), in-line defect inspection solutions, and analytical services through its laboratory in Switzerland. Their products support various applications, including the reliability of LEDs, GaN power transistors, solar cells, and nano-electronic devices, catering to semiconductor R&D, industrial production, and materials science.
