LED production yield improvement using advanced in-situ metrology systems
Currently the LED industry is heading towards a period of competitive consolidation.As LED performance and efficiency are already sufficient to outrun all conventional light sources,leading players in the field are now targeting a rigorous cost reduction due to the rapidly decreasing cost per lumen.Especially the epitaxial LED growth process provides significant cost reduction potential by increasing the MOCVD tool capacity and throughput combined with larger wafer sizes and well-prized silicon wafers.These measures require advanced in-situ monitoring to improve production yield and ensure process stability.Here we focus on tight control of LED growth for process optimization using advanced in-situ metrology.
