  • Patent number: 10586912
    Abstract: A plurality of transducer elements are formed. For each of the plurality of transducer elements, an electrode of the transducer element is formed on a first side of a support layer. A piezoelectric element of the transducer element is formed on the first side of the support layer. An interconnect of the transducer element is formed in the support layer. The support layer is thinned to expose a second side of the support layer. The interconnects of the plurality of transducer elements extend between the first side and the second side of the support layer. The second side of the support layer is bonded to a flexible layer with an adhesive material. Conductive fillers are disposed in the adhesive material. The interconnects of the plurality of transducer elements are each electrically coupled via the conductive fillers to the corresponding interconnect extending through the flexible layer.

  • Publication number: 20170062694
    Abstract: Techniques and structures for providing flexibility of a micromachined transducer array. In an embodiment, a transducer array includes a plurality of transducer elements each comprising a piezoelectric element and one or more electrodes disposed in or on a support layer. The support layer is bonded to a flexible layer including a polymer material, wherein flexibility of the transducer array results in part from a total thickness of a flexible layer. In another embodiment, flexibility of the transducer array results in part from one or more flexural structures formed therein.

  • Patent number: 9375850
    Abstract: Embodiments reduce capacitive cross-talk between micromachined ultrasonic transducer (MUT) arrays through grounding of the substrate over which the arrays are fabricated. In embodiments, a metal-semiconductor contact is formed to a semiconductor device layer of a substrate and coupled to a ground plane common to a first electrode of the transducer elements to suppress capacitive coupling of signal lines connected to a second electrode of the transducer elements.

  • Publication number: 20050094315
    Abstract: An information storage system includes a transducer having a loop of ferromagnetic material with pole tips separated by an nonferromagnetic gap located adjacent to a medium such as a rigid disk. During writing the separation between the pole tips and the media layer of the disk is a small fraction of the gap separation. Due to the small separation between the pole tips and the media layer, the magnetic field generated by the transducer and felt by the media has a larger perpendicular than longitudinal component, favoring perpendicular recording over longitudinal recording. The media may have an easy axis of magnetization oriented substantially along the perpendicular direction, so that perpendicular data storage is energetically favored. The transducer may also include a magnetoresistive sensor for reading magnetic information from the disk.
