  • Eliminating systematic process yield loss via precision wafer placement alignment
    Patent number: 7214552
    Abstract: A method for a semiconductor process includes correlating yield loss for the performance of a processing step in a semiconductor manufacturing process with the mechanical placement of the semiconductor substrate and, based on the correlation, placing semiconductor substrates in a position with sufficient placement precision to reduce yield loss below a predetermined threshold.
