ABSTRACT:
A signal line network on a substrate for interconnecting IC chips is programmable after manufacture to define the desired connections. The signal lines comprise line segments arranged end-to-end in both horizontal and vertical directions and are connectible at their ends and the vertical and horizontal segments are connectible at their crossings. A dedicated contact pad is connected to each segment. A plurality of bonding pads are adjacent several segments and each pad has arms extending across the several segments and are individually connectible to them. All connectible junctions comprise amorphous silicon antifuses which are normally insulators and are selectively programmable after the substrate is manufactured by applying a voltage pulse across the antifuse to render it conductive. The pads are arranged in a pattern in cells, all cells having the same pad pattern to facilitate probe connections for programming and testing.
