摘要:
In a silicon wafer two channels are etched in each street separated enough to bracket the saw. The channels may be shallow. The saw blade is positioned within the two channels so that the outer wall of each of the channels is beyond the outer edge of the saw. Cracks and the like caused by the saw terminate at the channels and so the adjoining chips are not injured. Damage of chips is reduced and the width of the streets is reduced.
