Abstract
A method for forming a microelectromechanical device may provide forming a first layer at least one of in or over a semiconductor carrier; forming a second layer at least one of in or over at least a central region of the first layer, such that a peripheral region of the first layer is at least partially free of the second layer; removing material under at least a central region of the second layer to release at least one of the central region of the second layer or a central region of the first layer; and/or removing material under at least the peripheral region of the first layer to such that the second layer is supported by the semiconductor carrier via the first layer.
