Abstract
The method for manufacturing a timepiece component is capable of thermocompensating a functional assembly including the timepiece component. The method includes at least the following actions: a) providing (e1) a substrate (1) of semiconductor or metallic material; b) proceeding with the deposition (e2) of a polycrystalline or monocrystalline silicon layer (5) on the substrate (1); c) releasing (e4) the timepiece component (10) from the substrate (1).
Claims22
A process for manufacturing a timepiece component which is able to thermally compensate a functional assembly comprising the timepiece component, wherein the process comprises:
- providing a substrate made of semiconductor material or metal material;
- carrying out a deposition of a polycrystalline- or monocrystalline-silicon layer onto the substrate;
- releasing the timepiece component from the substrate.
A timepiece component for a timepiece which is completely or partially made of polycrystalline silicon, wherein the timepiece component comprises a portion made of polycrystalline silicon uniformly doped over its entire thickness, or wherein the timepiece component comprises a portion made of polycrystalline silicon comprising a surface-doped layer.
