Abstract
Spectroscopic Ellipsometry (SE) has been adapted to a commercial III-V semiconductor Molecular Beam Epitaxy (MBE) system to monitor and control layer thickness and growth rate, substrate temperature, and ternary alloy composition. Results from a real-time experiment using feedback control based on SE measurements are presented. Algorithms are discussed for tracking of growth rate and temperature, and performance results are shown wing MBE ellipsometry data
