    Abstract: An inertial sensor has an interior filled with a relatively low viscosity fill gas. To that end, the inertial sensor has a housing forming the noted interior, and a movable component within the interior. The inertial sensor also has the noted fill gas within the interior. The fill gas has a viscosity that is less than the viscosity of nitrogen under like conditions. For example, when subjected to the same temperatures and pressures, the fill gas has a viscosity that is less than the viscosity of nitrogen.

    Abstract: A method is described for producing surface micromechanical structures having a high aspect ratio, a sacrificial layer being provided between a substrate and a function layer, trenches being provided by a plasma etching process in the function layer, at least some of these trenches exposing surface regions of the sacrificial layer. To increase the aspect ratio of the trenches, an additional layer is deposited on the side walls of the trenches in at least some sections, but not on the exposed surface regions of the sacrificial layer. In addition, a sensor is described, in particular an acceleration sensor or a rotational rate sensor.

    Abstract: A proof mass (11) for a MEMS device is provided herein. The proof mass comprises a base (13) comprising a semiconductor material, and at least one appendage (15) adjoined to said base by way of a stem (21). The appendage (15) comprises a metal (17) or other such material that may be disposed on a semiconductor material (19). The metal increases the total mass of the proof mass (11) as compared to a proof mass of similar dimensions made solely from semiconductor materials, without increasing the size of the proof mass. At the same time, the attachment of the appendage (15) by way of a stem (21) prevents stresses arising from CTE differentials in the appendage from being transmitted to the base, where they could contribute to temperature errors.
