Photoluminescence tool for concentration (AlGaN), LED characterization, layer thickness and Bow measurements

EUMETRYS, Associated with ETAMAX, distribute several tools for photoluminescence measurement. PLATO is a non-destructive mapping measurement system that uses PL(Photoluminescence) phenomenon. The photoluminescense analysis coupled with different laser sources can be used in multiple application:

• VCSEL DBR
• RF GAN
• LEDS
• Yellow PL
• POWER GAN
• SIC defect inspection

The PLATO 200 and PLATO 300 can measure wafer from all sizes for Al contents in AlGaN layer, Thin-film thickness of GaN layer and even Bow measurement.

Eumetrys is the exclusive distributor in Europe for ETAMAX product line.

MiPLATO-LED for specific LED challenges

The MIPLATO-LED ensures the challenges of LED technology are monitored properly using different sources and imaging methods.

The different features are:

• High-speed Micro PL Intensity Mapper with highly sensitive PMT
• R,G,B chip on wafer & Epi wafer measurement with size of 4″, 6”
• Simultaneous measurement of PL and Reflection (or Scattering) (patented)
• LED chip detection with leakage current
• Micro LED inspection.
• Low intensity, no PL signal, abnormal high PL intensity can be classified
• Chip indexing
• Defect coordinating and reporting
• Microscopic image observation of specific areas
• Spectral characteristics analysis possible by designating a specific area in PL Mapping Data (mapping possible)
• Signal measurement in selective wavelength range using a monochromator is possible (Option)
• Epi wafer inspection
