    Abstract: This disclosure provides systems, methods, and apparatus for fabricating electromechanical systems devices. In one aspect, a method of sealing an electromechanical systems device includes etching a sacrificial layer. The sacrificial layer is formed between a surface of a substrate and a shell layer and is etched through etch holes in the shell layer formed over the electromechanical systems device. The etch holes in the shell layer have a diameter greater than about one micron. The shell layer is then treated. A seal layer is deposited on the treated shell layer. The seal layer hermetically seals the electromechanical systems device.

    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.

    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.
