In recent years, gallium nitride-based (GaN) electronics have shown great promise for high-power RF devices in university and industrial research laboratories.  Single-wafer molecular beam epitaxy (MBE) systems have been the preferred epitaxial tools for growing these electronic materials.  However, moving these GaN-based devices into high-volume production requires uniform, repeatable growth on large (100mm) substrates.  This presentation will address the issues involved in scaling MBE growth of nitrides from single-wafer R&D demonstrations up to production on multiple 100mm wafers.
