Abstract

Described are various improved methods of forming electronic devices, electro-mechanical devices, force-sensing devices, and accelerometers. Also described are various improved electronic devices, electro-mechanical devices, force-sensing devices, and accelerometers. The device comprises a plurality of vibrating beams joined with a support portion and configured for movement relative to the support portion. A layer of electrically conductive material is disposed over at least some of the surface of the moveable portion and support portion, the layer comprising an inert or a noble material having a Young's modulus which is greater than that of elemental gold. Alternatively, the layer may comprise an inert material having a coefficient of expansion which is less than that of elemental gold.
