Abstract:
A sensor, in particular for the spatially resolved detection, includes a substrate, at least one micropatterned sensor element having an electric characteristic whose value varies as a function of the temperature, and at least one diaphragm above a cavity, the sensor element being disposed on the underside of the at least one diaphragm, and the sensor element being contacted via connecting lines, which extend within, on top of or underneath the diaphragm. In particular, a plurality of sensor elements may be formed as diode pixels within a monocrystalline layer formed by epitaxy. Suspension springs, which accommodate the individual sensor elements in elastic and insulating fashion, may be formed within the diaphragm.
Abstract:
System and method for forming an ALD assembly on a surface of a microelectromechanical system (MEMS) device comprises a substrate having a surface and the ALD assembly is at least partially disposed on the surface of the substrate, wherein the ALD assembly is at least one of hydrophobic and hydrophilic properties. The ALD layer further includes a first ALD and a second ALD. On the surface of the substrate, the first ALD is deposited in a first deposition cycle and the second ALD is deposited in a second deposition cycle. The ALD assembly further comprises a seed layer formed using atomic layer deposition and the ALD layer is at least partially disposed on the seed layer. In one example, the seed layer is formed from alumina (Al 2 O 3 ) and the ALD layer is formed from platinum (Pt). In alternate embodiment, on the seed layer, the first ALD is deposited in a first deposition cycle and the second ALD is deposited in a subsequent deposition cycle. The substrate is formed from silicon dioxide (SiO 2 ).
Abstract:
The present invention provides a 3D System ("3DS") MEMS architecture that enables the integration of MEMS devices with IC chips to form a System on Chip (So C) or System in Package (Si P). The integrated MEMS system comprises at least one MEMS chip, including MEMS transducers, and at least one IC chip, including not only MEMS processing circuitry, but also additional/auxiliary circuitry to process auxiliary signals. The MEMS and IC chips are bump bonded. The MEMS chip includes first and second insulated conducting pathways. The first pathways conduct the MEMS-signals between the transducers and the IC chip, for processing; and the second conducting pathways extend through the entire thickness of the MEMS chip, to conduct auxiliary signals, such as power, RF, I/Os, to the IC chip, to be processed the additional circuitry.

Une membrane (1) absorbante est fixée en suspension sur une face avant d'un substrat (2), sensiblement parallèlement au substrat (2), par au moins une structure alvéolée isolant thermiquement la membrane du substrat (2) et disposée dans un plan sensiblement perpendiculaire au substrat (2). Le détecteur peut comporter des bras (3) solidaires de la membrane (1) absorbante. Les structures alvéolées peuvent être disposées respectivement entre l'un des bras (3) et le substrat (2). La structure alvéolée peut être constituée par une pluralité de couches minces (6) superposées et séparées par des entretoises (7) ou par des rangées superposées d'arcades constituées par des couches minces. La structure alvéolée peut comporter un plot poreux.
