Latest Patents

One of her latest patents is titled "Low cost wafer level process for packaging MEMS three dimensional devices." This patent presents an apparatus and method for wafer-level hermetic packaging of MEMS devices of various shapes and form factors. The method involves bonding a glass cap wafer with fabricated micro-glassblown 'bubble-shaped' structures to the substrate glass/Si wafer. Metal traces on the substrate wafer facilitate signal transfer from the sealed cavity of the bubble to the outside world. This innovative packaging method utilizes a micro glass-blowing process to create 'bubble-shaped' glass lids, which are essential for vacuum packaging of three-dimensional MEMS devices.

Another significant patent is "Through-wafer interconnects for MEMS double-sided fabrication process (TWIDS)." This invention provides a high-aspect ratio low resistance through-wafer interconnect for double-sided fabrication of MEMS. It serves as an interconnection method and structure for co-integration of MEMS and integrated circuits or other microcomponents utilizing both sides of the wafer. The TWIDS method applied to a three-dimensional folded TIMU (timing inertial measurement unit) enables electrical signals to travel from sensors on the front side of the SOI wafer to electronic components on the back side, while allowing for the folding of an array of sensors into a three-dimensional shape.
