摘要： The encapsulated film bulk acoustic resonator (FBAR) device comprises a substrate, an FBAR stack over the substrate, an element for acoustically isolating the FBAR stack from the substrate, encapsulant covering the FBAR stack, and an acoustic Bragg reflector between the top surface of the FBAR stack and the encapsulant. The FBAR stack comprises an FBAR and has a top surface remote from the substrate. The FBAR comprises opposed planar electrodes and a piezoelectric element between the electrodes. The acoustic Bragg reflector comprises a metal Bragg layer and a plastic Bragg layer juxtaposed with the metal Bragg layer. The large ratio between the acoustic impedances of the metal of the metal Bragg layer and the plastic material of the plastic Bragg layer enables the acoustic Bragg reflector to provide sufficient acoustic isolation between the FBAR and the encapsulant for the frequency response of the FBAR device to exhibit minor, if any, spurious artifacts arising from undesirable acoustic coupling between the FBAR and the encapsulant.

摘要： The film acoustically-coupled transformer (FACT) has a first and second decoupled stacked bulk acoustic resonators (DSBARs). Each DSBAR has a lower film bulk acoustic resonator (FBAR), an upper FBAR atop the lower FBAR, and an acoustic decoupler between them FBARs. Each FBAR has opposed planar electrodes and a piezoelectric element between the electrodes. A first electrical circuit interconnects the lowers FBAR of the first DSBAR and the second DSBAR. A second electrical circuit interconnects the upper FBARs of the first DSBAR and the second DSBAR. In at least one of the DSBARs, the acoustic decoupler and one electrode of the each of the lower FBAR and the upper FBAR adjacent the acoustic decoupler constitute a parasitic capacitor. The FACT additionally has an inductor electrically connected in parallel with the parasitic capacitor. The inductor increases the common-mode rejection ratio of the FACT.

摘要： The decoupled stacked bulk acoustic resonator (DSBAR) device has a lower film bulk acoustic resonator (FBAR), an upper FBAR stacked on the lower FBAR, and an acoustic decoupler between the FBARs. Each of the FBARs has opposed planar electrodes and a layer of piezoelectric material between the electrodes. The acoustic decoupler has acoustic decoupling layers of acoustic decoupling materials having different acoustic impedances. The acoustic impedances and thicknesses of the acoustic decoupling layers determine the acoustic impedance of the acoustic decoupler, and, hence, the pass bandwidth of the DSBAR device. Process-compatible acoustic decoupling materials can then be used to make acoustic decouplers with acoustic impedances (and pass bandwidths) that are not otherwise obtainable due to the lack of process-compatible acoustic decoupling materials with such acoustic impedances.

摘要： A wellhead seal assembly that forms a metal-to-metal seal between inner and outer wellhead members and a face seal between inner wellhead members. The face seal is created by two opposing sealing surfaces on inner wellhead members that sealingly engage each other. The inner wellhead members that interact to form a face seal may be a casing hanger, bridging hanger, or lockdown hanger. A wicker profile formed on one of the opposing seal surfaces bites into the opposing seal surface in response to a load. The face seal is designed such that well pressure enhances the face seal.

摘要： A first catalog of items associated with item characteristics Cim, describing the items is converted into a display catalog of the items. A plurality of item parameters Pi are defined for the items of the first catalog. A first generation module generates a first identifier for each item in the first catalog. The first identifier comprises a series of the item characteristics for each of the parameters associated with the item. A hierarchy prioritizes item parameters and their associated characteristics. A second generation module generates a second identifier based on the first identifier and the hierarchy. The second identifier comprises a series of item characteristics that is a subset of the characteristics included in the first identifier. A display generator generates display catalog from the second catalog by selectively populating a display medium according to the priority of each characteristic and associated parameter of the second identifier.

摘要： A substrate defining a cavity comprising a wide, shallow first portion and a narrow, deep second portion is provided. The first portion of the cavity extends into the substrate from the front side of the substrate and is filled with sacrificial material. The second portion extends deeper into the substrate from the first portion. A device structure is fabricated over the sacrificial material. A release etchant is introduced from the back side of the substrate via the second portion of the cavity to remove from the first portion of the cavity the sacrificial material underlying the device structure. Removing from the first portion of the cavity the sacrificial material underlying the device structure by introducing the release etchant from the back side of the substrate via the second portion of the cavity allows the release etch to be performed without exposing the device structure to the release etchant. This allows the device structure to incorporate materials that have a low etch selectivity with respect to the sacrificial material.

摘要： The film acoustically-coupled transformer (FACT) has decoupled stacked bulk acoustic resonators (DSBARs), a first electrical circuit and a second electrical circuit. Each of the DSBARs has a lower film bulk acoustic resonator (FBAR), an upper FBAR and an acoustic decoupler. The upper FBAR is stacked on the lower FBAR and the acoustic decoupler is located between the FBARs. Each FBAR has opposed planar electrodes and a piezoelectric element between the electrodes. The first electrical circuit interconnects the lower FBARs. The second electrical circuit interconnects the upper FBARs. The FBARs of one of the DSBARs differ in electrical impedance from the FBARs of another of the DSBARs. The FACT has an impedance transformation ratio greater than 1:m2, where m is the number of DSBARs. The actual impedance transformation ratio depends on the ratio of the impedances of the FBARs.
