A MEMS device and a method for making a MEMS device are described. The MEMS device includes a support member, an optical device, and a flexible member. In one aspect, the flexible member is formed separately from the support member and the optical device. In one aspect, the flexible member is dimensioned to enable flex in one direction while maintaining stiffness in two orthogonal directions. In one fabrication embodiment, the MEMS device is formed by etching an opening into the structural layer to create a structural support member and an optical device. The structural support member and optical device are mounted on a support substrate with a sacrificial layer. A flexible member is conformally deposited over the structural support member and the optical device and then etched. The sacrificial layer is partially etched away to leave the structural support member anchored to the support substrate.

A multilayer micromirror structure that exhibits substantially no form change as a result of a given change in temperature is disclosed. A reflective layer is disposed on a substrate layer, and a counterbalancing structure is disposed on the structure in a way such that a neutral plane is located at a predetermined position relative to the substrate layer and the reflective layer. When forces are exerted at the neutral plane of such a structure, the structure attains a predetermined geometric form. A method of manufacture is disclosed wherein a substrate is etched to define a desired structure and a conformal layer of a masking material is deposited onto the etched substrate. Further etching exposes portions of the substrate and silicon is deposited to achieve another desired structure. Excess material is etched away to free the finished structure and a reflective layer is deposited onto the surface of the structure.
