Patents by Inventor HONGMEI XIE

HONGMEI XIE 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: 9731962
    Abstract: MEMS devices and methods for forming the same are provided. A first metal interconnect structure is formed on a first semiconductor substrate to connect to a CMOS control circuit in the first semiconductor substrate. A bonding layer having a cavity is formed on the first metal interconnect structure, and then bonded with a second semiconductor substrate. A conductive plug passes through a first region of the second semiconductor substrate, through the bonding layer, and on the first metal interconnect structure. A second metal interconnect structure includes a first end formed on the first region of the second semiconductor substrate, and a second end connected to the conductive plug. Through-holes are disposed through a second region of the second semiconductor substrate and through a top portion of the bonded layer that is on the cavity to leave a movable electrode to form the MEMS device.
