Abstract
MEMS structures and methods utilizing a locker film are provided. In an embodiment a locker film is utilized to hold and support a moveable mass region during the release of the moveable mass region from a surrounding substrate. By providing additional support during the release of the moveable mass, the locker film can reduce the amount of undesired movement that can occur during the release of the moveable mass, and preventing undesired etching of the sidewalls of the moveable mass.
