A trampoline arena includes a framework assembly having a plurality of frame elements defining an outwardly sloping outer wall, and a deck, a plurality of voids being defined between the framework elements. Masking layers are deposited on oxide layers present on opposite surfaces of the wafer, after which the masking layers are etched to expose regions of the underlying oxide layers. The method further includes stripping the sacrificial material through at least one opening formed on the at least one tab which is on the side of the switching device, and sealing the at least one opening with a capping material. Preferably, the inclining section is a linearly inclining section and the declining section is a linearly declining section. Other embodiments may be described and claimed.
