    摘要: A tightness testing method for a MEMS or small encapsulated component, the MEMS or small component being housed in a cavity of a carrier. The cavity being sealed and containing a gas having a different density to the density it would have if subjected to the pressure of the medium outside the cavity. The method measures the density of the gas contained in the cavity.

    摘要: The invention relates to inter-level realignment after a stage of epitaxy on a face (31) of a substrate (30), comprising the production of at least one initial guide mark (32) on the face of the substrate, this initial guide mark being designed so as to be transferred, during epitaxy, onto the surface of the epitaxied layer (36). The initial guide mark (32) is produced in such a way that, during epitaxy, its edges create growth defects that propagate as far as the surface of the epitaxied layer (36) to provide a transferred guide mark (37) on the surface of the epitaxied layer (36) reproducing the shape of the initial guide mark (32) and in alignment with the initial guide mark.

    摘要: A microelectromechanical (MEM) device includes a substrate, a structure, a travel stop, and a protective cap. The substrate has a surface, and the structure is coupled to, and movably suspended above, the substrate surface. The structure has at least an outer surface, and the travel stop coupled to the structure outer surface and movable therewith. The travel stop includes at least an inner peripheral surface that defines a cavity. The protective cap is coupled to the substrate and includes a stop section that is disposed at least partially within the travel stop cavity and is spaced apart from the travel stop inner peripheral surface. The travel stop and the protective cap stop section together limit movement of the structure in at least three orthogonal axes.
