Abstract
The invention relates to the production of a mechanical resonator with a planar monolithic vibrating structure machine in a crystalline material. Where the material is trigonal (1), trigonal (2) or hexagonal in structure, said material is cut in the [001] plane or, where said material is cubic in structure, said material is cut in the [111] plane and the vibration mode of order 2 is used. Where the material is tetragonal (1) or tetragonal (2) or hexagonal said material is cut in the [001] plane or where said material is cubic in structure said material is cut in the [001], [100], or [010] plane and the vibration mode of order 3 is used. The resonator thus has a natural material frequency isotropy (Δf=0).
