Used NIKON i7 #9068879 for sale

NIKON i7 is a wafer stepper designed for advanced 180nm node and below lithography applications. This ultra-high resolution pattern generation equipment achieves 1.2 line/space patterns and 200nm diameter contact holes at full cycle times of 66 seconds. The unique 1.2X reduction optics and advanced illumination system are combined with a long, stable operational lifetime and high stability. This combination of features make NIKON I 7 an ideal solution for high volume, cost effective lithography production. I7 is a 6-axis unit, allowing for efficient masking alignment and execution. Its robust mechanical design ensures long-term operation and maintains high accuracy and image reproducibility. Its ultra-fast auto alignment machine, which utilizes a large number of alignment marks, minimizes the time required to achieve accurate alignment. Its versatile auto-aborting tool allows frequent inspections during photoresist processing, ensuring only optimal exposures are used for production. The combination of both scan and step and repeat modes make I 7 an ideal choice for production of a variety of optical device sizes from chip-to-wafer. Its low power consumption and reduced footprint allow for reduced floor space management and improved air-conditioning efficiency. It is compatible with existing reticles and photoresist processing systems, allowing for the integration of a lithography asset without extensive memory and code re-calibration. NIKON i7 also offers excellent environmental protection features. Its built-in ozone treatment device filters out ultra-low concentration ozone and other gases released during exposure process, ensuring a safe working environment. Its petal shutter design allows for prevention of light leaks from reticle to wafer, maintaining sensitive exposures. The model also features an anti-vibration equipment to reduce noise and vibration, as well as an automatic safety interlocking door to protect the operator. Overall, NIKON I 7 is a highly reliable, cost-effective wafer stepper that is designed for advanced lithography processing. Its versatile combination of features make it an ideal choice for high volume production of optical devices and allows for efficient operation and long-term reliability.
