    摘要: One embodiment of the present invention sets forth a substrate contact for a MEMS device die, where the substrate contact is formed through an electrically insulative layer in the device die that is positioned between a handle wafer layer and a MEMS device layer formed on the handle wafer layer. The substrate contact serves as a path to ground for the MEMS handle wafer layer and is formed during the fabrication process of the MEMS device. One advantage of the disclosed invention is that a robust, low-impedance path to ground is provided for the MEMS handle wafer layer, with minimal impact on the process of fabricating a MEMS device.

    摘要: One embodiment of the present invention sets forth a method for decreasing a temperature coefficient of frequency (TCF) of a MEMS resonator. The method comprises lithographically defining slots in the MEMS resonator beams and filling the slots with oxide. By growing oxide within the slots, the amount of oxide growth on the outside surfaces of the MEMS resonator may be reduced. Furthermore, by situating the slots in the areas of large flexural stresses, the contribution of the embedded oxide to the overall TCF of the MEMS resonator is increased, and the total amount of oxide needed to decrease the overall TCF of the MEMS resonator to a particular target value is reduced. As a result, the TCF of the MEMS resonator may be reduced in a manner that is more effective relative to prior art approaches.

    摘要: An optical mirror system with multi-axis rotational control is disclosed. The mirror system includes an optical surface assembly, and at least one leg assembly coupled to the optical surface assembly. The at least one leg assembly supports the optical surface above a substrate.
