Researchers developed a new fabrication method for self-aligned micromechanical disk resonators. This innovation enables gigahertz frequencies with high quality factors (Q) in both air and vacuum.

Area of Science:

  • Microelectromechanical Systems (MEMS)
  • Materials Science
  • Electrical Engineering

Background:

  • Traditional fabrication methods for micromechanical resonators face challenges in achieving precise alignment, impacting performance.
  • Achieving high-frequency operation (GHz range) with high quality factors (Q) is crucial for advanced sensing and communication applications.

Purpose of the Study:

  • To introduce a novel fabrication methodology enabling self-alignment of micromechanical structures.
  • To demonstrate the performance of polysilicon micromechanical disk resonators fabricated using this new technique, focusing on resonance frequency and Q factor.

Main Methods:

  • Utilized a new fabrication process allowing self-alignment of the resonator's stem to the disk's center.
  • Fabricated polysilicon micromechanical disk resonators operating in a radial-contour mode.

  • Characterized resonator performance, including resonance frequency and Q factor, in both vacuum and air environments.
  • Main Results:

    • Achieved resonance frequencies up to 1.156 GHz with Q factors >2,650 at this frequency in both vacuum and air.
    • Demonstrated a 734.6-MHz resonator with Q factors of 7,890 (vacuum) and 5,160 (air).
    • The self-alignment technique significantly improved resonator balancing, enabling high Q at gigahertz frequencies for the first time.

    Conclusions:

    • The novel self-alignment fabrication method is effective for producing high-performance micromechanical disk resonators.
    • These resonators demonstrate potential for applications requiring high-frequency operation and high Q factors.
    • An equivalent electrical circuit model was developed to accurately predict the performance of these disk resonators.
