  • Patent number: 11920932
    Abstract: A wafer-level assembly method for a micro hemispherical resonator gyroscope includes: after independently manufactured glass substrates are softened and deformed at a high temperature, forming a micro hemispherical resonator on the glass substrate; forming glass substrate alignment holes at both ends of the glass substrate by laser ablation; aligning and fixing a plurality of identical micro hemispherical resonators on a wafer fixture by using the alignment holes as a reference, and then performing operations by using the wafer fixture as a unit to implement subsequent processes that include: releasing the micro hemispherical resonators, metallizing the surface, fixing to the planar electrode substrates, separating the wafer fixture and cleaning to obtain a micro hemispherical resonator gyroscope driven by a bottom planar electrode substrate.
    Type: Grant
