  • Publication number: 20220289566
    Abstract: A method of manufacturing a MEMS device. The MEMS device has a cavity in which a beam will move to change the capacitance of the device. After most of the device build-up has occurred, sacrificial material is removed to free the beam within the MEMS device cavity. Thereafter, exposed ruthenium contacts are exposed to fluorine to either: dope exposed ruthenium and reduce surface adhesive forces, form fluorinated Self-Assembled Monolayers on the exposed ruthenium surfaces, deposit a nanometer passivating film on exposed ruthenium, or alter surface roughness of the ruthenium. Due to the fluorine treatment, low resistance, durable contacts are present, and the contacts are less susceptible to stiction events.

  • Patent number: 8529021
    Abstract: A method of continuously ejecting liquid includes providing a liquid ejection system that includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate includes a MEMS transducing member that extends over at least a portion of the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. The compliant membrane includes an orifice. Liquid is provided under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate by a liquid supply. A drop of liquid is caused to break off from the liquid jet by selectively actuating the MEMS transducing member which causes a portion of the compliant membrane to be displaced relative to the liquid chamber.
