How to Choose the Best Calibration Wafer Standard for Optical Inspection Tools
In modern semiconductor manufacturing, optical inspection tools are only as reliable as the standards used to calibrate them. As critical dimension control tightens and defect budgets shrink, selecting the right calibration wafer standard is no longer a formality—it is a foundational requirement for process control, tool matching, and regulatory confidence. At Applied Physics., we work […]
Why SSIS Tools Must Be Calibrated to NIST-Traceable Particle Size Standards
SSIS tools (Surface Scanning Inspection Systems) must be calibrated to NIST-traceable particle size standards to ensure particle sizing is consistent, comparable, and actionable across tools, fabs, and time. When particle size data is accurate and standardized, contamination control teams can identify sources faster, reduce false alarms, improve tool matching, and protect yield—especially at advanced nodes […]
