Abstract
A module for LSI chips includes an orthogonal array of sets of pads and fan-out metallization for a large number of chips. Running parallel to the sides of the chips and the fan-out area are several parallel prefabricated, thin film engineering change interconnection lines terminating in pads adjacent to the fan-out. The pads are arranged to permit discretionary connections of the fan-out pads to the engineering change pads with minimal crossovers by means of short fly wires. A staggered pad arrangement minimizes potential crossovers and maximizes the number of interconnection lines that can be fabricated.
