Abstract
Abstract A customizable interconnect circuit wherein a universal substrate of minimum layers is completely customized by programmable conductive links placed only on the top layer of the substrate. The customizable circuit having high density of orthogonally placed X- and Y-conductors capable of interconnecting closely spaced large-scale integrated circuits or discrete electrical components. By utilizing a plurality of interconnect cells regularly spaced throughout a universal, fixed substrate, interconnect routing from overlying electrical components or integrated circuits can be more directly routed to target areas.
