摘要: A semiconductor chip in which stress on the effective stress on the substrate is reduced in order to reduce bowing. To reduce the effective stress, a stress compensation layer is provided on the backside of the chip. The stress compensating layer produces a stress opposite of that produced by the IC. Thus the overall or effective stress on the substrate is reduced.
