Our advanced inspection application utilizes a high-precision confocal line sensor to perform comprehensive, non-contact analysis of CMP polishing pads.  The confocal line sensor’s high-speed scanning capability ensures rapid data acquisition, enabling real-time analysis using custom algorithms to evaluate critical pad characteristics and detect defects.  

The application can inspect and measure a wide range of geometric features, including: 

• Diameter: Precise measurement of pad dimensions to ensure compliance with specifications.
• Trench Width and Depth: Accurate assessment of groove dimensions to maintain optimal slurry flow and polishing performance.
• Feature Pitch and Width: Evaluation of patterned features to verify uniformity and consistency across the pad surface.
• Feature Coplanarity: Analysis of surface planarity to ensure even polishing pressure distribution.
• Pad Substrate Flatness: Detection of deviations in substrate flatness that could impact wafer quality. 

 In addition to geometric measurements, our system excels at identifying surface defects such as: 

• Scratches: Detection of linear marks that could affect polishing uniformity.
• Dents: Identification of localized depressions that may alter pad performance.
• Debris: Recognition of foreign particles that could contaminate the polishing process.
