INTERLEAVED MULTI-LAYER REDISTRIBUTION LAYER PROVIDING A FLY-BY TOPOLOGY WITH MULTIPLE WIDTH CONDUCTORS

Abstract:

A redistribution assembly may have multiple layers. Each layer may include a signal conductor and a ground conductor. The width of the ground conductors may exceed the width of the signal conductors. In addition, the layers may be vertically positioned over each other to form the redistribution layer assembly. The conductors may be interleaved such that the ground conductor of a top layer is vertically positioned over the signal conductor for a bottom layer and the signal conductor of the top layer is positioned over the ground conductor of the bottom layer. Multi-layer redistribution layer assemblies may be used with stacks of dies in an IC package to create a fly-by topology that provides electrical continuity in the X, Y and Z dimensions.
