Abstract: Disclosed are process control systems and methods incorporating a crystal microbalance (CM) (e.g., a quartz crystal microbalance (QCM)) into gas flow line(s) entering and/or exiting a processing chamber.

CM(s) incorporated into gas flow lines entering and/or exiting a processing chamber can provide precise measurements for process monitoring at minimal cost.
