    Abstract: In an integrated MEMS device, moving silicon parts with smooth surfaces can stick together if they come into contact. By roughening at least one smooth surface, the effective area of contact, and therefore surface adhesion energy, is reduced and hence the sticking force is reduced. The roughening of a surface can be provided by etching the smooth surfaces in gas, plasma, or liquid with locally non-uniform etch rate. Various etch chemistries and conditions lead to various surface roughness.

    Abstract: The invention relates to controllable Fabry-Perot interferometers which are produced with micromechanical (MEMS) technology. Producing prior art interferometers includes a risk of deterioration of mirrors during the etching of the sacrificial layer (123). According to the solution according to the invention at least one layer (103, 105, 114, 116) of the mirrors is made of silicon-rich silicon nitride. In the inventive Fabry-Perot interferometer it is possible to avoid or reduce using silicon oxide in the mirror layers whereby the risk of deterioration of the mirrors is reduced. It is also possible to use mirror surfaces with higher roughness, whereby the risk of the mirrors sticking to each other is reduced.

    Abstract: A micromechanical component has a substrate, a first intermediate layer which is situated thereupon, and a first layer which is situated thereupon and is structured down to the first intermediate layer. A second intermediate layer is situated above the first layer. A second layer is situated on the former, at least one movable micromechanical structure being structured into the second layer. The second intermediate layer is removed in a sacrificial zone beneath the movable micromechanical structure and the first intermediate layer is partially removed in zones beneath the first layer. The movable micromechanical structure is provided with at least one stop surface on a bottom face, this stop surface being contactable with a zone of the first layer which is supported by the first intermediate layer by deflection of the movable micromechanical structure. A method for producing such a micromechanical component is also described.

    Abstract: A useful layer (1) is initially attached by a sacrificial layer (2) to a layer (3) forming a substrate. Before etching of the sacrificial layer (2), at least a part of the surface (4, 5) of at least one of the layers in contact with the sacrificial layer (2) is doped. After etching of the sacrificial layer (2), the surface (4, 5) is superficially etched so as to increase the roughness of its doped part. After doping, a mask (9) is deposited on a part of the useful layer (1) so as to delineate a doped zone and a non-doped zone of the surface (4, 5), one of the zones forming a stop after the superficial etching phase.

    Abstract: A method for fabrication of substrate having a nano-scale surface roughness is presented. The method comprises: patterning a surface of a substrate to create an array of spaced-apart regions of a light sensitive material; applying a controllable etching to the patterned surface, said controllable etching being of a predetermined duration selected so as to form a pattern with nano-scale features; and removing the light sensitive material, thereby creating a structure with the nano-scale surface roughness. Silanizing such nano-scale roughness surface with hydrophobic molecules results in the creation of super- hydrophobic properties characterized by both a large contact angle and a large tilting angle. Also, deposition of a photo-active material on the nano-scale roughness surface results in a photocathode with enhanced photoemission yield. This method also provides for fabrication of a photocathode insensitive to polarization of incident light.
