摘要

Process for mass production of GaN and its related alloys, InGaN and AlGaN, have been optimized to achieve high device yield and low cost of ownership. Here we present some of the latest results obtained from ATX 2000 HT Planetary Reactor~® in a configuration of 7×2" which provides unique uniformity capabilities due to the two fold rotation of the substrates. GaN single layers with background electron concentrations below 5·10~(16) cm~(-3) and intended doping levels up to 10~(18) cm~(-3) p-type and 10~(20) cm~(-3) n-type with state of the art homogeneities have been achieved. Thickness homogeneities have been shown to be better than 1 % standard deviation on full 2" wafers, while composition uniformity of ternary material is determined by room temperature photoluminescence mappings. Low temperature photoluminescence and reflectance spectra of single layer GaN revealed free exciton transitions.
