Integrated circuit package having inductance loop formed from a bridge interconnect

Abstract

An integrated circuit package includes an inductance loop formed from a connection of lead wires and one or more input/output (I/O) package pins. In one embodiment, the inductance loop is formed from a first wire which connects a first bonding pad on the integrated circuit chip to a first I/O pin of the package and a second wire which connects a second bonding pad on the chip to a second I/O pin of the package. To complete the inductor loop, the first and second I/O pins are connected by a conductive bridge between the pins. The bridge may be formed by making the I/O pins have a unitary construction. In another embodiment, the bridge is formed by a metallization layer located either on the surface of the package substrate or within this substrate. The I/O pins are preferably ones which are adjacent one another; however, the loop may be formed from non-adjacent connections of I/O pins based, for example, on loop-length requirements, space considerations, and/or other design or functional factors. By forming the inductor loop within the limits of the integrated circuit package, a substantial reduction in space requirements is realized, which, in turn, promotes miniaturization. Also, the integrated circuit may be implemented in any one of a variety of systems, at least one parameter of which is controlled by the length of the inductor loop of the package.
