Used KLA / TENCOR Alpha Step IQ #9361397 for sale

KLA / TENCOR Alpha Step IQ is a wafer testing and metrology equipment designed to provide high precision measurements of films on wafer surfaces. The system is based on a patented dual wavelength interferometer design, allowing for precise measurements of low and high refractive index films on patterned or non-patterned wafers. KLA Alpha Step IQ uses patented dual wavelength optical interferometry technology, combining two near infrared wavelengths to measure sub-nanometer film thicknesses. The unit is optimized for different types of films including dielectrics, photoresists, anti-reflection coatings, and thin metal films. TENCOR ALPHASTEP IQ offers important advantages over traditional contact metrology techniques as it produces highly accurate non-contact analyses. The machine's Process Monitor Mode provides a real-time inspection of the wafer's surface, identifying any imperfections or deviations. The low noise and high accuracy of TENCOR Alpha Step IQ also make it ideal for detecting trace contamination and profiling surface roughness. Alpha Step IQ offers exceptional repeatability, wafer-to-wafer and tool-to-tool. This enables the user to get consistent measurements, eliminating the need for frequent calibrations. This reduces the time and cost of inspections, while maintaining high precision measurements. The tool is a versatile wafer testing platform, offering a range of development, analysis, and review capabilities, providing users with the ultimate flexibility. KLA ALPHASTEP IQ can provide 3D line profiles, critical threshold curves, and defect characterization reports. These allow users to quickly diagnose device issues and optimize their manufacturing processes. ALPHASTEP IQ is a compact tool designed to operate in a laboratory setting, as well as in a production line environment. It is a cost-effective asset for measuring films, with a unique design and premium components that make it a dependable, reliable, and accurate wafer testing and metrology platform.
