    Abstract: A method is proposed for anisotropic etching of micro- and nanofeatures in silicon substrates using independently controlled etching steps and polymer deposition steps which succeed one another alternatingly, the quantity of polymer deposited decreasing in the course of the polymer deposition steps, thus preventing any underetching of the micro- and nanofeatures.

    Abstract: A method of manufacturing a semiconductor device, which can effectively form a trench having a high aspect ratio with relatively simple steps. An initial trench is formed in a silicon substrate by a reactive ion etching using an oxide film mask as an etching mask. After forming a protection oxide film on an inside surface of the trench, a part of the protection oxide film at which positions at a bottom surface of the trench is removed by a reactive ion etching, so that an etching of the silicon substrate is advanced through the bottom surface of the trench. Furthermore, the step for forming the protection oxide film and the step for re-etching the bottom surface of the trench are repeatedly performed, so that a depth of the trench becomes a predetermined depth. These steps are performed in a common chamber by using plasma processed with switching gases to be introduced to the chamber.

    Abstract: A method of producing etched structures in substrates by anisotropic plasma etching, wherein an essentially isotropic etching operation and side wall passivation are performed separately and in alternation, with the substrate being a polymer, a metal or a multicomponent system, and portions of the side wall passivation layer applied during passivation of the side wall are transferred to the exposed side surfaces of the side wall during the subsequent etching operations, so the entire method is anisotropic as a whole.

    Abstract: The invention relates to fluid paths in etchable materials. Fluid paths are formed by forming a cavity through a substrate material with a first dry removal process to produce a first surface of the cavity. The first surface of the cavity is associated with a first roughness. The first surface of the cavity is etched with a second wet removal process to reduce the first roughness and produce a second roughness associated with the first surface of the cavity. A coating is applied to the first surface of the cavity to produce a second surface to improve wettability of the first or second surface of the cavity, reduce in size or number gas nucleation sites in the first or second surface of the cavity, reduce the amount of debris associated with the first roughness carried by the fluid flow, and/or improve hydrophilicity of the first or second surface.
