Patents by Inventor Alexandra Efimovskaya

Alexandra Efimovskaya has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10167190
    Abstract: An apparatus and method for wafer-level hermetic packaging of MicroElectroMechanical Systems (MEMS) devices of different shapes and form factors is presented in this disclosure. The method is based on bonding a glass cap wafer with fabricated micro-glassblown “bubble-shaped” structures to the substrate glass/Si wafer. Metal traces fabricated on the substrate wafer serve to transfer signals from the sealed cavity of the bubble to the outside world. Furthermore, the method provides for chip-level packaging of MEMS three dimensional structures. The packaging method utilizes a micro glass-blowing process to create “bubbleshaped” glass lids. This new type of lids is used for vacuum packaging of three dimensional MEMS devices, using a standard commercially available type of package.

  • Patent number: 9611138
    Abstract: A high-aspect ratio low resistance through-wafer interconnect for double-sided (TWIDS) fabrication of microelectromechanical systems (MEMS) serves as an interconnection method and structure for co-integration of MEMS and integrated circuits or other microcomponent utilizing both sides of the wafer. TWIDS applied to a three dimensional folded TIMU (timing inertial measurement unit) provides a path for electrical signals from sensors on the front side of the SOI wafer to electronic components on the back side of the wafer, while enabling folding of an array of sensors in a three dimensional shape.
