Abstract:
A reconfigurable substrate, comprising:at least one signal line layer stack, each signal line layer stack defined to include: two substantially parallel insulating layers; and a signal line layer interposed between the two insulating layers and substantially parallel to the insulating layers; a reconfigurable portion including a conductive isolation layer set selected from a group of conductive isolation layer sets including: a first conductive isolation layer set comprising at least one conductive isolation layer adjacent to the at least one signal line layer stack and substantially parallel to the at least one signal line layer stack; and a second conductive isolation layer set comprising the first conductive isolation layer set and at least one additional conductive isolation layer; wherein the substrate has a higher performance level when configured with the second conductive isolation layer set than when configured with the first conductive isolation layer set.
