    Abstract: Systems and methods that protect CMOS layers from exposure to a release chemical are provided. The release chemical is utilized to release a micro-electromechanical (MEMS) device integrated with the CMOS wafer. Sidewalls of passivation openings created in a complementary metal-oxide-semiconductor (CMOS) wafer expose a dielectric layer of the CMOS wafer that can be damaged on contact with the release chemical. In one aspect, to protect the CMOS wafer and prevent exposure of the dielectric layer, the sidewalls of the passivation openings can be covered with a metal barrier layer that is resistant to the release chemical. Additionally or optionally, an insulating barrier layer can be deposited on the surface of the CMOS wafer to protect a passivation layer from exposure to the release chemical.

    Abstract: La présente invention se rapporte à un procédé de fabrication d'une pièce de micro-mécanique, notamment d'une pièce d'horlogerie mécanique, par gravure à partir d'un substrat, le procédé comprenant au moins une première étape effectuée par gravure ionique réactive profonde (DRIE) avec les paramètres ajustés afin de réaliser une gravure produisant les flancs essentiellement verticaux, ainsi qu'une deuxième étape effectuée par gravure ionique réactive profonde (DRIE) avec les paramètres ajustés afin de réaliser une gravure produisant les flancs inclinées sous un angle prédéterminé par rapport à la verticale, la première et la deuxième étape étant réalisées de manière continue, sans arrêt de gravure. En outre, la présente invention se rapporte également à une pièce de micro-mécanique, notamment une pièce d'horlogerie mécanique, fabriquée à l'aide de ce procédé, ayant un profil de flancs latéraux prédéterminé.

    Abstract: An apparatus (36) includes a motion amplification structure (52), an actuator (54), and a sense electrode (50) in proximity to the structure (52). The actuator (54) induces an axial force (88) upon the structure (52), which causes a relatively large amount of in-plane motion (108) in one or more beams (58, 60) of the structure (52). When sidewalls (98) of the beams (58, 60) exhibit a skew angle (126), the in-plane motion (108) of the beams (58, 60) produces out-of-plane motion (110) of a paddle element (62) connected to the end of the beams (58, 60). The skew angle (126), which results from an etch process, defines a degree to which the sidewalls (98) of beams (58, 60) are offset or tilted from their design orientation. The out-of-plane motion (110) of element (62) is sensed at the electrode (50), and is utilized to determine an estimated skew angle (126).

    Abstract: The present invention is related to a method for producing a Micro-Electromechanical System (MEMS) device, comprising:
    - Depositing a sacrificial oxide layer on a substrate,
    - Depositing one or more structural layers on said sacrificial oxide layer and patterning said structural layers to form a structure,
    - Removing the sacrificial layer by vapour etching,
    to thereby release a portion of said structure,

    wherein the step of depositing a sacrificial oxide layer comprises depositing a first layer (7) of a first sacrificial oxide having a first density, and depositing on said first layer a second layer (8) of a second sacrificial oxide, the second layer having a higher density than the first layer. The method allows to protect a first structural layer deposited on and in contact with the second sacrificial oxide layer, said vapour etching step having low selectivity of said first structural layer towards said first sacrificial oxide layer. Said first structural layer may be a silicon nitride layer protecting the backplate of a MEMS microphone.
