摘要
We have developed a large-scale metal-organic vapor phase epitaxy (MOVPE) reactor. The growth rates of AlN and AlGaN were compared with those calculated using the parasitic chemical reaction model. The calculated results were in good agreement with the experimental results over the entire 8" wafer. To experimentally investi-gate the extent of the gas-phase prereaction between the precursors and ammonia, the results of epitaxy were compared with those for a 6"-type reactor. The growth of AlN and AlGaN at relatively high rates without any significant gas-phase prereaction was demonstrated.
