  • Patent number: 9294064
    Abstract: A planar capacitor includes, in part, a first metal line forming spiral-shaped loops around one of its end point, and a second metal line forming spiral-shaped loops between the loops of the first metal line. The first and second metal lines are coplanar, formed on an insulating layer, and form the first and second plates of the planar capacitor. The planar capacitor may be used to form a filter. Such a filter includes a first metal line forming first spiral-shaped loops, a second metal line forming second spiral-shaped loops, and a third metal line—coplanar with the first and second metal lines—forming loops between the loops of the first and second metal lines. The filter further includes a first inductor coupled between the first and third metal lines, and a second inductor coupled between the second and third metal lines.

  • Patent number: 9275876
    Abstract: Systems and methods for preventing warpage of a semiconductor substrate in a semiconductor package. A continuous or uninterrupted stiffener structure is designed with a recessed groove, such that passive components, such as, high density capacitors are housed within the recessed groove. The stiffener structure with the recessed groove is attached to the semiconductor substrate using anisotropic conductive film (ACF) or anisotropic conductive paste (ACP). The stiffener structure with the recessed groove surrounds one or more semiconductor devices that may be formed on the semiconductor substrate. The stiffener structure with the recessed groove does not extend beyond horizontal boundaries of the semiconductor substrate.

  • Patent number: 9264013
    Abstract: Systems for reducing magnetic coupling in integrated circuits (ICs) are disclosed. Related components and methods are also disclosed. The ICs have a plurality of inductors. Each inductor generates a magnetic flux that has a discernible axis. To reduce magnetic coupling between the inductors, the flux axes are designed so as to be non-parallel. In particular, by making the flux axes of the inductors non-parallel to one another, magnetic coupling between the inductors is reduced relative to the situation where the flux axes are parallel. This arrangement may be particularly well suited for use in diplexers having a low pass and a high pass filter.
