摘要:
A multilayer capacitor comprises separate terminals on at least three sides, and on as many as six sides. The capacitor can be fabricated in a large number of different configurations, types, and sizes, depending upon the target application. The separate terminals that are disposed on different sides of the capacitor can be readily coupled to a variety of different adjacent conductors, such as die terminals (including bumpless terminals or bars), IC package terminals (including pads or bars), and the terminals of adjacent discrete components. Methods of fabrication, as well as application of the capacitor to an electronic assembly, are also described.

To provide high-speed, low inductance capacitive decoupling, an integrated circuit (IC) package includes capacitors positioned within the mounting region between a die and an IC package substrate. A variety of types and sizes of capacitors and substrates can be employed in a variety of geometrical arrangements. In some embodiments, capacitors are sandwiched between die terminals or bumps and the substrate conductors or pads, while in other embodiments, capacitors are positioned between bar-type conductors on the surface of the IC package substrate. Methods of fabrication, as well as application of the package to an electronic assembly and to an electronic system, are also described.

In one embodiment of the invention, an embedded enclosure includes a power plane and first and second ground planes. The power plane has a power surface and a power periphery, and couples power to signals of an integrated circuit operating at a fundamental frequency. The first and second ground planes have first and second ground surfaces and first and second ground peripheries, respectively. The first and second ground planes couple ground to the signals. The first and second ground planes are separated from the power plane by first and second distances, respectively. The first and second ground surfaces are larger than the power surface. The first and second ground peripheries extend at least third and fourth distances from the power periphery, respectively. The third and fourth distances are N and M times larger than the first and second distances, respectively.

A capacitor assembly having one or more capacitors embedded in the core layer of a package having integrated circuits (ICs) mounted thereon. Each embedded capacitor has plural pairs of first and second electrodes and the package core layer has plural sets of first and second vias dispersed over the pairs of electrodes and being connected thereto. A metal layer is provided on the core layer and includes a first portion having at least one metal strip and a second portion, electrically isolated from each strip. Each metal strip is positioned such that it is extended to overlie both the first electrode of a distinct pair of electrodes and the second electrode of an adjacent, succeeding pair of electrodes and effects a mutual electrical connection between them through first and second vias associated therewith, respectively. A wiring layer which may be a dielectric interlevel connection layer, provided on the metal layer, has plural sets of third vias that are disposed over the center of the capacitor such that adjacently disposed sets of third vias alternate between contacting the individual ones of the metal strips and contacting the second portion of the metal layer to provide interlayer electrical connections therethrough, respectively, to wirings or terminals in the package. The individual metal strips associated with the first portion of the metal layer are to be applied with one of the power and ground reference signals of the package assembly and the second portion thereof is to be applied with the other one of the power and ground voltages. These capacitors may be employed as bypass capacitors in a package assembly for integrated circuits.

摘要:
An electronic assembly includes multiple discrete capacitors (504, FIG. 5), which are surface mounted to or embedded within an electronic housing, such as an integrated circuit package (1504, FIG. 15). One or more side terminals (510) of adjacent capacitors are electrically connected through lateral connections (512, 620, FIGS. 5, 6). These lateral connections provide an extremely low lateral inductance current path between the discrete capacitors.
