Claim 0:
1. A method of manufacturing timepiece components comprising the following steps:
a) providing a substrate comprising a first silicon layer, a second silicon layer and, in between, an intermediate silicon oxide layer,
b) etching the first silicon layer to form therein the timepiece components,
c) releasing from the substrate a wafer formed by at least all or part of the etched, first silicon layer and comprising 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, and
f) detaching the timepiece components from the wafer.
