    Abstract: In one embodiment, a method of forming an out-of-plane electrode includes forming an oxide layer above an upper surface of a device layer, etching an etch stop perimeter defining trench extending through the oxide layer, forming a first cap layer portion on an upper surface of the oxide layer and within the etch stop perimeter defining trench, etching a first electrode perimeter defining trench extending through the first cap layer portion and stopping at the oxide layer, depositing a first material portion within the first electrode perimeter defining trench, depositing a second cap layer portion above the deposited first material portion, and vapor releasing a portion of the oxide layer with the etch stop portion providing a lateral etch stop.

    Abstract: The invention relates to a method for producing a micromechanical component and to a corresponding micromechanical component. The production method comprises the following steps: providing a substrate (1) with a monocrystalline starting layer (1c) which is exposed in structured regions (3a-3e), said structured regions (3a-3e) having an upper face (O) and lateral flanks (F), wherein a catalyst layer (2), which is suitable for promoting a silicon epitaxial growth of the exposed upper face (O) of the structured monocrystalline starting layer (1c), is provided on the upper face (O), and no catalyst layers (2) are provided on the flanks (F); and carrying out a selective epitaxial growth process on the upper face (O) of the monocrystalline starting layer (1c) using the catalyst layer (2) in a reactive gas atmosphere in order to form a micromechanical functional layer (3').

    Abstract: A silicon pressure sensor (10) shows an epitaxial layer (epilayer) (21,20) wrapped up around the edge of a cavity (15), which may be defined by an oxide layer etched away. The epitaxial layer (21,20) forms a membrane (19) with a piezoresistor (18). Alternatively a capacitance sensor may be used. Vent holes (14) are shown as vertical slots. Epitaxial silicon layer (17) grows as a single crystal on the side walls of the vent holes (14) and pinch them off by forming plugs (17) as an epitaxial seal (episeal).
