Abstract:
A single Micro-Electro-Mechanical System (MEMS) sensor chip is provided, for measuring multiple parameters, referred to as multiple degrees of freedom (DOF). The sensor chip comprises a central MEMS wafer bonded to a top cap wafer and a bottom cap wafer, all three wafer being electrically conductive. The sensor comprises at least two distinct sensors, each patterned in the electrically conductive MEMS wafer and in at least one of the top and bottom cap wafer. Insulated conducting pathways extend from electrical connections on the top or bottom cap wafers, through at least one of the electrically conductive top cap and bottom cap wafers, and through the electrically conductive MEMS wafer, to the sensors, for conducting electrical signals between the sensors and the electrical connections. The two or more distinct sensors are enclosed by the top and bottom cap wafers and by the outer frame of MEMS wafer.
Abstract:
Für ein Mikrofon mit vergrößertem Rückvolumen wird ein Hohlraumgehäuse vorgeschlagen, das zumindest eine Bodenplatte und eine Abdeckung umfasst, die den Hohlraum definieren und umschließen. Auf der Bodenplatte istein Mikrofonwandler, üblicherweise ein MEMS-Bauteil neben einem Schallführungselement montiert. Mikrofonwandler und Schallführungselement sind mit einer Abtrennung gegen die Bodenplatte abgedichtet und trennen das Frontvolumen von einem Rückvolumen unterhalb der Abdeckung. Das Schallführungselementstellt einen Schallkanal zur Verfügung, der eine Öffnung in der Abdeckung mit dem Vorvolumen verbindet. Das Schallführungselement schließt dicht an die Abdeckung an und dichtet so den Schallkanal gegen das Rückvolumen ab.
Abstract:
A thermal printhead die is formed from an SOI structure as a MEMS device. The die has a printing surface, a buried oxide layer, and a mounting surface opposite the printing surface. A plurality of ink delivery sites are formed on the printing surface, each site having an ink-receiving and ink-dispensing structure. An ohmic heater is formed adjacent to each structure, and an under-bump metallization (UBM) pad is formed on the mounting surface and is electrically connected to the ohmic heater, so that ink received by the ink-delivery site and electrically heated by the ohmic heater may be delivered to a substrate by sublimation. A through-silicon-via (TSV) plug may be formed through the thickness of the die and electrically coupled through the buried oxide layer from the ohmic heater to the UBM pad. Layers of interconnect metal may connect the ohmic heater to the UBM pad and to the TSV plug.

The invention relates to a method for producing a micromechanical component, the component produced using said method, and a use of the micromechanical component during the production of a micromechanical sensor component. In order to produce the micromechanical component, a first structured layer is first produced on the front side of a semiconductor wafer, and the semiconductor wafer is etched from the front side using a first trench etching step in accordance with said first structured layer. A second structured layer is then applied to the rear side of the semiconductor wafer, and the semiconductor wafer is etched from the rear side using a second trench etching step in accordance with the second structured layer. The invention is characterized in that a through-hole from the front side to the rear side is produced in the semiconductor wafer using the first and the second trench etching step.
