  • Patent number: 12255381
    Abstract: Antenna modules employing three-dimensional (3D) build-up on mold package to support efficient integration of radio-frequency (RF) circuitry, and related fabrication methods. The antenna module includes a RF transceiver whose circuitry is split over multiple semiconductor dies (“dies”) so different semiconductor devices can be formed in different semiconductor structures. The antenna module is provided as a 3D build-up on mold package to reduce lengths of die-to-die (D2D) interconnections between circuits in different dies. First and second die packages that include respective first and second dies encapsulated in respective first and second mold layers are coupled to each other in a vertical direction in a 3D stacked arrangement with active faces of the first and second dies facing each other to provide a reduced distance between the active faces of the first and second dies. An antenna is stacked on the second die package to provide an antenna(s) for the antenna module.

  • Publication number: 20250047262
    Abstract: An acoustic device includes circuit elements, such as analog circuit components, between the first and second substrate and coupled to an acoustic resonator to form an acoustic filter within the acoustic device. In some examples, forming the circuit elements between the first substrate and the second substrate includes forming the first circuit elements in insulating material on the second substrate before coupling the second substrate to a first side of the first substrate. The circuit elements disposed between the first and second substrates may include capacitors, inductors, and electrical interconnects coupled to the acoustic resonator on the first substrate. Additional features may be included in the insulating material. The acoustic device avoids the need for bulky analog components coupled to the acoustic resonator via long interconnects through a package substrate, making it possible to reduce an acoustic device's package size.

  • Publication number: 20240421790
    Abstract: A package includes a device that includes electrodes disposed on a piezoelectric layer on a first, front side of a first substrate and vertical interconnect accesses (vias) that extend through the substrate to couple the electrodes to a second, back side of the first substrate. The vias may be through-substrate vias (TSVs). Employing a first substrate (e.g., silicon) in which vias can be formed, the electrodes on the front side can be coupled to interconnects on the back side to minimize electrical path distances to and from the device for a higher a Q factor. Also, a capacitor may be formed on a second, back side of the substrate and coupled to an electrode of the device by a via rather than having an electrical path from a first substrate, to an external capacitor on a package substrate. A thermal conductive path is also reduced for improved heat dissipation.

  • Publication number: 20240347913
    Abstract: An antenna module as a radio-frequency (RF) integrated circuit (IC) semiconductor die (“die”) with an integrated antenna substrate. The die with the integrated antenna substrate can be provided as part of a single IC chip that is fabricated as part of a wafer-level fabrication process as an example. The antenna elements are formed in one more antenna layers as part of an antenna substrate. The antenna layers may be formed as re-distribution layers (RDLs) for example to support smaller line-spacing (LS) and/or smaller pitched metal interconnects for forming and interconnecting to smaller wavelength antenna elements for supporting higher frequency communications. The antenna substrate is formed on a semiconductor wafer of an IC as part of the die. In this manner, the antenna layers can be formed as part of a wafer-level fabrication process used to form the die to form the antenna layers.

  • Patent number: 11984874
    Abstract: Surface acoustic wave (SAW) filter packages employing an enhanced thermally conductive cavity frame for heat dissipation, and related fabrication methods are disclosed. The SAW filter package also includes a cavity frame comprising a perimeter structure and a cavity inside the perimeter structure coupled to a substrate of a piezoelectric material that contains interdigital transducers (IDTs). A cap substrate is disposed on the perimeter structure of the cavity frame to enclose an air cavity inside the perimeter structure between a substrate and the cap substrate. In exemplary aspects, to effectively dissipate heat generated in the SAW filter package to maintain the desired performance of the SAW filter, the cavity frame is comprised of a material that has an enhanced thermal conductivity. The heat generated in the SAW filter package can more effectively be dissipated, particularly at edges and corners of the cavity frame where hot spots can particularly occur.
