Patent number: 11465177Abstract: A PMUT ultrasound transducer includes a number of PMUT transmitting elements in a membrane layer. Behind each PMUT transmitting element is a cavity in the membrane layer. The cavities are partially or completely filled with a damping material to reduce ringing of the PMUT transmitting elements. Suitable damping materials include polymers, e.g., soft epoxies, benzocyclobutene or polyimide that are dispersed into the cavities or a phase changing material such as Parylene that precipitates out of a gas phase as a polymer when cured.Type: GrantFiled: May 16, 2019Date of Patent: October 11, 2022Assignee: FUJIFILM SONOSITE, INC.Inventors: Gregg Frey, Wei Li

Publication number: 20060058706Abstract: Backing blocks, transducer arrays and methods are provided for thermal cycle survivability. By decoupling a portion of the backing block from a case used to contain the transducer stack, the greater thermal expansion properties of most backing blocks may be minimized. For example, a rim is formed on the backing block material. The rim is bonded to the case structure while other portions of the backing block remain free of bonding to the case structure. During thermal cycling or other temperature changes, the backing block may be less likely to expand or bulge and crack, delaminate or damage transducer elements or other transducer materials.Type: ApplicationFiled: August 19, 2004Publication date: March 16, 2006Inventor: Gregg Frey

Publication number: 20060028099Abstract: A matching layer is formed as a composite, such as a 2-2 or a 1-3 composite. The base material forms some portion, such as 5 or more percentage by volume, of the composite matching layer and volume. The in-fill, bonding or acoustically isolating material holds the sections of base material together and provides for control of the stiffness and cross coupling. By using an electrically conductive base material, electrical conductivity is provided from a top surface to a bottom surface. The composite is easily manufactured using dicing of a base material, filling of the kerfs and curing the filled kerfs.Type: ApplicationFiled: August 5, 2004Publication date: February 9, 2006Inventor: Gregg Frey

Publication number: 20050225210Abstract: Electrical connection is provided in a transducer stack through a backing block. A flexible circuit is sandwiched between pieces of acoustic attenuating material. For example, 2 to 200 or more flexible circuits are stacked in alternating layers with pieces of acoustically attenuating material. The alternating layers are then connected together to form a backing block with Z-axis electrical connection. The top surface of the connected backing block includes a plurality of exposed electrical traces from the flex circuit. Since flex circuits are used, the electrical traces are precisely aligned along one dimension. Since pre-formed acoustic attenuating material pieces are used, precise alignment is provided along a second or orthogonal dimension. The substrate holding the electrical traces in the flexible circuits provides more stability and allows for easier connection to circuit boards as compared to individual strips of metal.Type: ApplicationFiled: April 1, 2004Publication date: October 13, 2005Inventors: Stephen Englund, Ellen Rowland, Grazyna Palczewska, Gregg Frey, Todor Sheljaskow, Lisa Fearn, Vaughn Marian, Nelson Oliver, Walter Wilser, Worth Walters

Publication number: 20050203409Abstract: Electrical interconnects are provided for CMUTs. For example, electrodes within the silicon substrate, such as the electrodes at the bottom of the void below membranes, are interconnected together within the substrate. The interconnected electrode may then be used as the grounding electrode. By providing interconnection within the substrate and below the membranes, space for vias and the associated connection between the electrodes on an exposed surface of the substrate is minimized. As another example, an electrical conductor is formed on the side of the silicon substrate rather than the top of the substrate. Conductors on the side may allow routing signals from a top surface to a bottom surface without large wire bonding pads. Alternatively, conductors on the edge provide additional space for wire bonding pads. As yet another example, polymer material used as a matching or protection layer is formed on the top surface of the CMUT with electrical traces routed within the polymer.Type: ApplicationFiled: March 12, 2004Publication date: September 15, 2005Inventors: Gregg Frey, Grazyna Palczewska, Stephen Barnes, Mirsaid Bolorforosh

Publication number: 20050042424Abstract: Matching layers are provided, including: electrically conductive acoustic matching layers, methods for conducting electric current through matching layers, methods for manufacturing multi-dimensional arrays using conductive matching layers, and multi-dimensional arrays with electrically conducting matching layers. Matching layers with conductors aligned for providing electrical conduction through the thickness or range dimension of the matching layer are provided. For example, vias, aligned magnetic particles, or conductive films at least partially or entirely within the matching layer of each element allow electrical conduction from the transducer material to a ground foil or flex circuit. By using multiple electrical conductive matching layers, a gradation in acoustic impedance for better matching is provided while allowing dicing of the entire stack, including the matching layers and the electroceramic material, in one step.Type: ApplicationFiled: August 22, 2003Publication date: February 24, 2005Inventors: Gregg Frey, Todor Sheljaskow, Walter Wilser, Worth Walters, Nelson Oliver
