Assignee: APPLIED MATERIALS, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method of determining scribing offsets, comprising:
forming a mask above a semiconductor wafer, wherein the semiconductor wafer comprises a plurality of dies separated from each other by streets;
patterning the mask and the semiconductor wafer with a laser scribing process, wherein the patterning provides openings in the streets, wherein one or more of the openings comprises an S-shaped pattern;
removing the mask;
subsequent to removing the mask, measuring scribing offsets of the openings relative to the streets by measuring an offset at a plurality of locations along the S-shaped pattern and determining an average offset, the average offset including both a translational offset and an angular offset; and
using the average offset as an offset correction for processing a subsequent semiconductor wafer.
