    Abstract: Embodiments of the present invention relate to methods and systems for making a microelectromechanical system MEMS device comprising supplying an etchant to etch one or more sacrificial structures of the system in a chamber. A process parameter relating to the pressure within the chamber is monitored as a function of time to provide an indication of the extent of the etching of the one or more sacrificial structures.
