Abstract
Abstract A customizable circuit using a programmable interconnect and a compatible TAB chip bonding design. The programmable interconnect comprises layers of wire segments forming programmable junctions rather than continuous wires. This segmentation is performed with an offset from line to line in each layer such that the ends of the segments in each layer form along diagonal lines having a pitch determined by the basic wire segment length. The terminal ends of each of these segments are positioned in a plane such that the segments may be connected by short lengths to form the desired interconnect. The links which join the line segments represent the customization of the otherwise undedicated interconnect. The TAB chip bonding design uses a carrier tape to bond the integrated circuit chips to the programmable interconnect. Also disclosed are methods for forming the interconnect and the TAB chip bonding design.
