    Abstract: A process for fabricating a suspended microelectromechanical system (MEMS) structure comprising epitaxial semiconductor functional layers that are partially or completely suspended over a substrate. A sacrificial release layer and a functional device layer are formed on a substrate. The functional device layer is etched to form windows in the functional device layer defining an outline of a suspended MEMS device to be formed from the functional device layer. The sacrificial release layer is then etched with a selective release etchant to remove the sacrificial release layer underneath the functional layer in the area defined by the windows to form the suspended MEMS structure.

    Abstract: A method for creating a semiconductor structure is provided. In accordance with the method, a semiconductor substrate (101) is provided over which is disposed a sacrificial layer (103), and which has a thin single crystal semiconductor layer (105) disposed over the sacrificial layer (103). An opening (107) is then created which extends through the semiconductor layer (105) and into the sacrificial layer (103). The semiconductor layer (105) is then epitaxially grown to a suitable device thickness, thereby resulting in a device layer. The semiconductor layer is grown such that the resulting device layer extends over the opening (107), and such that the surface of the portion of the device layer extending over the opening is single crystal silicon.
