HB-LED Epitaxial Inspection for R&D and Production

In the rapidly growing industry of high power LED manufacturing, there are constant efforts to reduce costs and improve quality. Electroluminescence provides a nondestructive technique for spectral and electrical testing of epi wafers with correlation to device-level performance.

Bruker's electroluminescent system, LumiMap, offers the most accurate measurements of wavelength and Vf variation, minimizing end-of-line binning and improving yield.
