Patent ID: 7527998

Claim:
A method of making at least two types of microelectromechanical systems (MEMS) devices, the at least two types of MEMS devices having different release states after removal of sacrificial material, the method comprising: providing a substrate; forming a first electrically conductive layer over at least a portion of the substrate; forming a first sacrificial layer over at least a portion of the first conductive layer; forming a plurality of electrically conductive moveable elements over the first sacrificial layer; and forming a plurality of flexure controllers over the substrate configured so as to operably support the electrically conductive moveable elements after the sacrificial layer is removed, wherein at least a portion of at least one flexure controller of the plurality of flexure controllers is overlying and operably supporting at least one movable element of the plurality of electrically conductive movable elements; the first sacrificial layer being removable to thereby release the MEMS devices and form a plurality of cavities of different depths between the first electrically conductive layer and the movable elements.
