Patent attributes
A method for fabricating a Microelectromechanical System (MEMS) resonator includes providing a dielectric substrate defining a resonator and depositing a conductive coating having a resistivity of approximately 1 to 50 μΩ-cm on that substrate by Atomic Layer Deposition (ALD). A resonator fabricated according to this process includes a dielectric substrate defining a resonator and a conductive coating having a resistivity of approximately 1 to 50 μΩ-cm for electrically coupling the resonator to electronics. Another method for fabricating a MEMS resonator includes providing a dielectric substrate defining a resonator, depositing an aluminum oxide film on that substrate by ALD, and depositing a noble metal film on the aluminum oxide film, also by ALD.
