  • Patent number: 9443810
    Abstract: A flip-chip employing an integrated cavity filter is disclosed comprising an integrated circuit (IC) chip comprising a semiconductor die and a plurality of conductive bumps. The plurality of conductive bumps is interconnected to at least one metal layer of the semiconductor die to provide a conductive “fence” that defines an interior resonator cavity for providing an integrated cavity filter in the flip-chip. The interior resonator cavity is configured to receive an input RF signal from an input transmission line through an input signal transmission aperture provided in an internal layer in the semiconductor die. The interior resonator cavity resonates the input RF signal to generate the output RF signal comprising a filtered RF signal of the input RF signal, and couples the output RF signal on an output signal transmission line in the flip-chip through an output transmission aperture provided in the aperture layer.

    Abstract: An upper planar capacitor is spaced above a lower planar capacitor by a dielectric layer. A bridged-post inter-layer connector couples the capacitances in parallel, through first posts and second posts. The first posts and second posts extend through the dielectric layer, adjacent the upper and lower planar capacitors. A first level coupler extends under the dielectric layer and couples the first posts together and to a conductor of the lower planar capacitor, and couples another conductor of the lower planar capacitor to one of the second posts. A second level coupler extends above the dielectric layer, and couples the second posts together and to a conductor of the upper planar capacitor, and couples another conductor of the upper planar capacitor to one of the first posts.

  • Patent number: 9245940
    Abstract: An inductor design on a wafer level package (WLP) does not need to depopulate the solder balls on the die because the solder balls form part of the inductor. One terminal on the inductor couples to the die, the other terminal couples to a single solder ball on the die, and the remaining solder balls that mechanically contact the inductor remain electrically floating. The resulting device has better inductance, direct current (DC) resistance, board-level reliability (BLR), and quality factor (Q).
