Abstract: The method for manufacturing timepiece hairsprings according to the invention comprises the following successive steps: a) forming hairsprings in a wafer, b) forming a thermal compensation layer on the hairsprings, c) identifying the hairsprings having a stiffness within a predetermined range, d) optionally, detaching from the wafer the hairsprings identified in step c), e) modifying the other hairsprings so that the stiffness of at least some of them is within the predetermined range, f) detaching from the wafer these other hairsprings and, if they have not been detached in step d), the hairsprings identified in step c). This method makes it possible to reduce manufacturing dispersions between the hairsprings.

Abstract: The micromechanical clockwork part is cut from a plate-like silicon substrate. The cut edges of the part include portions intended to serve as contact surfaces arranged to slide against corresponding contact zones of another micromechanical part in a clockwork piece. The cut edges have a ribbed surface including an alternating set of ribs and furrows, the ribs and the furrows being straight and each contained in a plane parallel to the plate. Moreover, the ribs and furrows which the cut edges have form a stepped pattern on the cut edge, with first intervals in which the spacing separating the ribs from one another is equal to a first distance, and at least one second interval in which the spacing between the ribs is equal to a second distance different from the first distance.

Abstract: Disclosed is a method including the following steps: a) providing a substrate including a first silicon layer, a second silicon layer and an intermediate silicon oxide layer therebetween; b) etching the first silicon layer in order to form the timepiece components therein; c) releasing from the substrate a wafer formed by at least all or part of the etched, first silicon layer and including the timepiece components; d) thermally oxidizing and then deoxidizing the timepiece components; e) forming by thermal oxidation or deposition a silicon oxide layer on the timepiece components; f) detaching the timepiece components from the wafer.

Abstract: A method of manufacturing a timepiece component, such as a balance, an oscillating mass or a wheel, comprises a micro-manufacturing technique, such as the DRIE technique. The method may comprise forming at least one member in or at the periphery of the structure, of a material different from that of the structure. This member is typically metal and is formed by electro-forming using a cavity of the structure as a mold.
