Description
Simplify the preparation of calibration wafers with Thermo Scientific™ SURF-CAL™ Particle Size Standards, for calibration and maintenance of Scanning Surface Inspection Systems (SSIS). Available particle sizes correspond to the calibration point sizes required by instrument manufacturers.
Thermo Fisher Scientific™, along with the Semiconductor Industry and SEMI, have established specific particle sizes to be used when calibrating Scanning Surface Inspection Systems. Working with instrument manufacturers, we created the SURF-CAL™ product line to meet SEMI standard guidelines.
- Available sizes are considered to be critical sizing nodes as defined by the International Technology Roadmap for Semiconductors (ITRS).
- By depositing SURF-CAL™ NIST™ traceable polystyrene latex spheres (PSL) on specially selected wafers, you can perform periodic calibration checks and compare your scanner with scanners at other locations.
- You can also assess the performance of your SSIS at critical stages in the manufacturing process.
- All products are suspended in deionized, filtered water in 50mL bottles at a concentration of 3 × 108 particles per mL.
Note:
Products PD1100 and smaller are also available at 1010 particles per mL for applications using the aid of a Differential Mobility Analyzer (DMA) or other size exclusionary techniques.
