    摘要： Embodiments of the invention describe hermetic encapsulation for MEMS devices, and processes to create the hermetic encapsulation structure. Embodiments comprise a MEMS substrate stack that further includes a magnet, a first laminate organic dielectric film, a first hermetic coating disposed over the magnet, a second laminate organic dielectric film disposed on the hermetic coating, a MEMS device layer disposed over the magnet, and a plurality of metal interconnects surrounding the MEMS device layer. A hermetic plate is subsequently bonded to the MEMS substrate stack and disposed over the formed MEMS device layer to at least partially form a hermetically encapsulated cavity surrounding the MEMS device layer. In various embodiments, the hermetically encapsulated cavity is further formed from the first hermetic coating, and at least one of the set of metal interconnects, or a second hermetic coating deposited onto the set of metal interconnects.

    摘要： An accelerometer includes a mass, suspended by a beam, and associated conductive paths. Each conductive path is subjected to a magnetic field, such that, when a time varying signal is applied to the conductive paths, a characteristic resonant frequency is produced, and when the mass experiences an acceleration, a respective change in the resonant frequency is produced that may be interpreted as acceleration data. Embodiments include methods of manufacturing an accelerometer and systems and devices incorporating the accelerometer.

    摘要： This invention relates to inductive inertial sensors employing a magnetic drive and/or sense architecture. In embodiments, translational gyroscopes utilize a conductive coil made to vibrate in a first dimension as a function of a time varying current driven through the coil in the presence of a magnetic field. Sense coils register an inductance that varies as a function of an angular velocity in a second dimension. In embodiments, the vibrating coil causes first and second mutual inductances in the sense coils to deviate from each other as a function of the angular velocity. In embodiments, self-inductances associated with a pair of meandering coils vary as a function of an angular velocity in a second dimension. In embodiments, package build-up layers are utilized to fabricate the inductive inertial sensors, enabling package-level integrated inertial sensing advantageous in small form factor computing platforms, such as mobile devices.
