Below are two distinct examples demonstrating procedural integration and decision-making frameworks. Semiconductor Wafer Inspection Workflow Thermal metrology in semiconductor manufacturing focuses on defect detection, material characterization, and process optimization. The workflow for lock-in thermography (LIT) in wafer inspection includes: Pre-Inspection Preparation: Wafers undergo cleaning and dehydration to remove contaminants that could interfere with thermal signal accuracy. Baseline thermal profiles are established using reference wafers. Thermal Stimulation: A modulated infrared laser (e.g., 1064nm wavelength) heats the wafer surface in a controlled pattern. The modulation frequency (typically 1–50 Hz) is selected based on the expected defect depth (shallow defects require higher frequencies).
