Group-III nitride growth in production scale MOVPE systems

We have developed the AIX 2000 G3 HT MOVPE system for large scale production of nitride semiconductors. Extensive numeric modeling of the reactor chamber has enabled us to establish process windows for the growth of nitride semiconductors. We report excellent wafer to wafer, on-wafer and run to run uniformities across all wavelength regions accessible to the InGaN material system. Laser action in GaN epitaxial layers and in InGaN/GaN quantum well heterostructures at optical excitation was achieved in a wide spectral interval from 370 nm up to 470 nm. The working temperature reached 580 K for the best multiple quantum well structures
