Methods and devices for monitoring and controlling thin film processing

摘要

Thin film processing systems and methods are provided having a moving deposition sensor capable of translation and/or rotation in a manner that exposes the sensor to thin film deposition environments in a flux region substantially the same as the deposition environments experienced by one or more moveable substrates during a selected deposition period. In one embodiment, a thin film monitoring and control system is provided wherein one or more moveable substrates and a moveable deposition sensor are moved along substantially coincident trajectories in a flux region of a thin film deposition system for a selected deposition period. Systems and methods of the present invention may include SC-cut quartz crystal microbalance sensors capable of excitation of at least two different resonant modes.
