    Abstract: A multi-material resonant thin film beam for a micromechanical sensor having a zero temperature coefficient of frequency (TCF) which is the resonant frequency shift with temperature change. One of the materials may be polysilicon and the other material may be silicon nitride or silicon oxide. Each material has a different thermal coefficient of expansion. The proportion of the various materials is adjusted and the specific geometries are determined so that the TCF is zero. One embodiment is a microbeam composed of two polysilicon thin films with a silicon nitride thin film inserted between the polysilicon films. The thickness of the silicon nitride film may be adjusted to trim the TCF to zero. The film of nitride instead may be placed on one side of a polysilicon film to form a beam. Dual or multiple beam resonators likewise may be made with several materials. The nitride may be placed in the shank areas which join and secure the ends of the beams. Such zero TCF beams may be incorporated in microsensor structures for measuring pressure, temperature, strain and other parameters.

    Abstract: The invention relates to an inertial sensor comprising a frame to which at least two seismic bodies are connected by resilient means such as to be movable in a suspension plane, and transducers to keep the seismic bodies vibrating and determine a relative movement of the seismic bodies relative to one another, characterized in that the seismic bodies have a single shape and a single mass, and in that the seismic bodies comprise interlocking parts such that the seismic bodies are nested inside one another while being movable in the suspension plane relative to the other of the seismic bodies, the seismic bodies having centres of gravity that coincide with one another. The invention also relates to a method for manufacturing such a sensor.

    Abstract: The invention relates to a device comprising a base substrate(700) with a micro component (702) attached thereto. Suitably it is provided with routing elements (704) for conducting signals to and from said component (702). It also comprises spacer members (706) which also can act as conducting structures for routing signals vertically. There is a capping structure (708) of a glass material, provided above the base substrate (700), bonded via said spacer members (706), preferably by eutectic bonding, wherein the capping structure (708) comprises vias (710) comprising metal for providing electrical connection through said capping structure. The vias can be made by a stamping/pressing method entailing pressing needles under heating to soften the glass and applying pressure, to a predetermined depth in the glass. However, other methods are possible, e-g- drilling, etching, blasting.
