Thermo Scientific SURF-CAL Particle Size Standards
Simplify the preparation of calibration wafers with these particle size standards.
Manufacturer: Thermo Scientific PD2000
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 x 108 particles per mL.
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.
