Abstract:
A multi-chip module and method of fabricating a multi-chip module. The multi-chip module includes: a substrate having a top surface and a bottom surface and containing multiple wiring layers, first pads on the top surface of the substrate and second pads on the bottom surface of the substrate; a first active component attached to a first group of the first pads and a second active component attached to a second group of the first pads; wherein at least one pad of the second pads is a split pad having a first section and a non-contiguous second section separated by a gap, the first section connected by a first wire of the multiple wires to a pad of the first group of first pads and the second section is connected by a second wire of the multiple wires to a pad of the second group of first pads.
