    Abstract: In a method for manufacturing a micromechanical membrane structure, a doped area is created in the front side of a silicon substrate, the depth of which doped area corresponds to the intended membrane thickness, and the lateral extent of which doped area covers at least the intended membrane surface area. In addition, in a DRIE (deep reactive ion etching) process applied to the back side of the silicon substrate, a cavity is created beneath the doped area, which DRIE process is aborted before the cavity reaches the doped area. The cavity is then deepened in a KOH etching process in which the doped substrate area functions as an etch stop, so that the doped substrate area remains as a basic membrane over the cavity.

    Abstract: A method for manufacturing a semiconductor device having a movable portion includes the steps of: forming a trench on a semiconductor layer so that the trench reaches an insulation layer; and forming a movable portion by etching a sidewall of the trench so that the semiconductor layer is separated from the insulation layer. The steps of forming the trench and forming the movable portion are performed by a reactive ion etching method. The insulation layer disposed on the bottom of the trench is prevented from charging positively in the step of forming the trench. The insulation layer disposed on the bottom of the trench is charged positively in the step of forming the movable portion.

    Abstract: According to the invention, a substrate (2) contained in an enclosure (1) containing an atmosphere (5) that is maintained at low pressure by a device (6, 7) for generating a vacuum is subjected to plasma etching. Plasma generation means (8) generate a plasma (9) which acts on the surface (2a) of the substrate (2). The etching method subjects the substrate (2) to an alternating succession of steps comprising: an attack step using a plasma of etching gas coming from an etching gas source (19), a second step of passivation by means of a plasma of passivation gas coming from a passivation gas source (20), and a pulse step of selective depassivation by the action of a plasma of a cleaning gas coming from a cleaning gas source (21) and serving to remove the polymer from the bottom zones of cavities (2b) more effectively than does the etching gas. This makes it possible to make cavities (2b) having an aspect ratio greater than 30, and to do so at higher speed, with good selectivity relative to the mask protecting the substrate (2).
