  • Publication number: 20190288658
    Abstract: A method and structure for a transfer process for an acoustic resonator device. In an example, a bulk acoustic wave resonator (BAWR) with an air reflection cavity is formed. A piezoelectric thin film is grown on a crystalline substrate. A first patterned electrode is deposited on the surface of the piezoelectric film. An etched sacrificial layer is deposited over the first electrode and a planarized support layer is deposited over the sacrificial layer, which is then bonded to a substrate wafer. The crystalline substrate is removed and a second patterned electrode is deposited over a second surface of the film. The sacrificial layer is etched to release the air reflection cavity. Also, a cavity can instead be etched into the support layer prior to bonding with the substrate wafer. Alternatively, a reflector structure can be deposited on the first electrode, replacing the cavity.

  • Patent number: 10303617
    Abstract: An electronic system includes a host device and a storage device. The storage device includes a first memory device that is accessed by the host device by units of a byte through a byte accessible interface and a second memory device that is accessed by the host device by units of a block through a block accessible interface. The storage device performs an internal data transfer between the first memory device and the second memory device based on an internal transfer command that is provided through the block accessible interface from the host device. The electronic system may efficiently support the access by units of a byte and the access by units of a block between the host device and the storage device by performing internal data transfer in the storage device using the internal transfer command that is modified from the existing block access command.

  • Publication number: 20190044493
    Abstract: An elliptical-shaped resonator device. The device includes a bottom metal plate, a piezoelectric layer overlying the bottom metal plate, and a top metal plate overlying the piezoelectric layer. The top metal plate, the piezoelectric layer, and the bottom metal plate are characterized by an elliptical shape having a horizontal diameter (dx) and a vertical diameter (dy), which can be represented as ellipse ratio R=dx/dy. Using the elliptical structure, the resulting bulk acoustic wave resonator (BAWR) can exhibit equivalent or improved insertion loss, higher coupling coefficient, and higher quality factor compared to conventional polygon-shaped resonators.
