Facilities

INML is currently equipped with two state-of-the-art Molecular Beam Epitaxy (MBE) reactors to provide semiconductor wafer growth foundry services. MBE-I is designed for providing (In, Ga, Al – As, Sb) epitaxial wafers, while MBE-II is designed to provide (In, Ga, Al – N) epitaxial wafers. This is the only (III-As / Sb + III-N) combined MBE system at UCLA.
