Method of applying the analysis of scrub mark morphology and location to the evaluation and correction of semiconductor testing, analysis, and manufacture

摘要

By examining scrub mark properties (such as position and size) directly, the performance of a wafer probing process may be evaluated. Scrub mark images are captured, image data measured, and detailed information about the process is extracted through analysis. The information may then be used to troubleshoot, improve, and monitor the probing process.
