  • Patent number: 7829424
    Abstract: 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.

  • Patent number: 5895968
    Abstract: A semiconductor device assembly having external connections, including power supply connections such as to a power source or ground, is made without resort to bond fingers. Rather, external connections are directly made from a semiconductor die to a conductive layer. The conductive layer is disposed on one surface of a printed wring board and is divided into electrically insulated conductive segments. Each of the conductive segments is connected to an external connection, and includes one or more interconnects that can be directly connected to a semiconductor die. The conductive segments are surrounded by an array of bond fingers which serve to connect the semiconductor die to further external connections, such as signal connections. The present invention is especially advantageous in the fabrication of pin grid array (PGA) and ball grid array (BGA) type integrated circuit packages.
