The ThinkLaser SigmaClean redefines wafer identification with its soft-marking process, designed specifically for cleanroom semiconductor workflows. Rather than removing substrate material, the laser alters surface properties to form marks, removing the risk of debris generation common to standard laser marking.
This system generates crisp, OCR-scannable identifiers for wafers. All marking output adheres to SEMI requirements, ensuring traceability holds up across multiple subsequent manufacturing steps. It integrates smoothly into existing wafer handling sequences, preserving wafer integrity and keeping contamination risks minimal throughout high-volume fab runs.
