  • Method and apparatus for improving force control in wafer scribing
    Patent number: 7807479
    Abstract: When scribing a substrate, the precise location of the outer peripheral edge of the substrate on a stage is determined and movement of a scribe tool is controlled to first bring the scribe tool into engagement with the substrate at a location inwardly of the outer peripheral edge of the substrate. After a downwardly directed force of predetermined magnitude exerted by the scribe tool has been attained and stabilized, the scribe tool is moved along the substrate to form a scribe line.
