A pattern of contacts that includes high speed transmitter contacts disposed in a first portion of the pattern, where the high speed transmitter contacts are disposed in transmitter differential pairs. High speed receiver contacts are disposed in a second portion of the pattern, where the first portion of the pattern is not interspersed with the second portion of the pattern, and the high speed receiver contacts are disposed in receiver differential pairs. At least one unbroken line of other contacts is disposed between the first portion of the pattern and the second portion of the pattern, where the other contacts do not contain any high speed transmitter contacts and high speed receiver contacts. Low speed IO contacts are disposed in a third portion of the pattern, where the third portion of the pattern is disposed in an interior portion of the pattern relative to both the first portion of the pattern and the second portion of the pattern. Substantially all of the contacts are disposed at a standard pitch one from another on a single contact surface.

The present invention is directed to a method of fabricating an integrated circuit package having decoupling capacitors using a package design conceived for use without decoupling capacitors. The package is implemented with a minimal redesign of the original design and not requiring any redesign of the signal trace pattern. The invention involves replacing top and bottom bond pads with via straps and then covering the top and bottom reference planes with a dielectric layer having conductive vias that electrically connect with the underlying via straps. Planes having the opposite polarity of the underlying reference plane are then formed on the dielectric layer. These planes include an array of bonding pads in registry with the vias. Decoupling capacitors are mounted to the top of the package and electrically connected with the plane on top of the package and the immediately underlying reference plane without the electrical connections to the capacitors passing through the signal planes of the package.

Embodiments of the invention include a semiconductor integrated circuit package that includes a substrate having an integrated circuit die attached thereto. The substrate further includes at least one signal layer having a plurality of electrical signal traces formed thereon. The package includes a discrete non-active electrical component mounted on the package so that the integrated circuit die is electrically connected with an electrical signal trace of the package through the discrete non-active electrical component. And in one particular implementation, the discrete non-active electrical component comprises a capacitive element arranged in series between the electrical signal traces and the die so that the capacitor operates as a package mounted AC coupling capacitor.

摘要:
A family of package substrates adapted to receive a family of integrated circuits having different sizes and provide electrical connections between the integrated circuits and a circuit board. Each package substrate in the family includes a package substrate having a die side and a circuit board side. The package substrate has a size that is consistent for all of the package substrates in the family of package substrates. The die side has integrated circuit contacts disposed in a pattern designed to make electrical connections to a given integrated circuit in the family of integrated circuits for which the package substrate is designed, as defined by locations of contacts on the given integrated circuit. The circuit board side has circuit board contacts disposed in a pattern and with functional assignments that are consistent for all of the package substrates in the family of package substrates.
