Abstract

 

This paper reviews results from growing LED structures on 200 mm sapphire and (111) silicon in a single wafer configuration Crius® Close Coupled Showerhead (CCS) reactor. By maintaining good temperature uniformity throughout the process state of the art uniformities were achieved on both substrate materials, including a PL peak wavelength at ~470 nm with standard deviation of _ ~1 nm for an MQW grown on (111) Silicon.
