Used NIKON i7A #293764351 for sale

NIKON i7A is NIKON latest and most advanced E-Beam Wafer Stepper, offering proven speed and precision for exposure scanning, high-accuracy alignment, self-controlled exposure consistency, and high resolution. I7A provides manufacturers an advanced lithography equipment for the production of nano-scale devices and ultra-fast exposure scanning. NIKON i7A is capable of a maximum scan speed of more than 1,000 steps per second, providing the fastest exposure time, helping to reduce total time-to-market. It utilizes a proved electro-optical system that features NIKON Adaptive Stage Settle Technology (ASST), which provides the most advanced alignment accuracy to date. The alignment accuracy achieved with i7A is 35 times higher than with conventional systems and is achieved by the integration of NIKON optical lens, and stage advances. An innovative dual scan unit also helps to reduce exposure distortion. This machine is designed to match the accelerations and decelerations as the stepper is scanning, including the combined action of both the exposure source and stage movements. The combination of dual scan and exposure source matching eliminates exposure distortion and greatly improves the accuracy of exposure results. NIKON i7A also provides the highest resolution exposure available, achieved from the integration of NIKON large aperture exposure source, a high-resolution motor, and a high-dynamic alignment tool. The combination of these features helps manufacturers achieve the best optical resolution. Finally, it incorporates a Multiple Exposure Compensation Asset (MECS), designed to help improve the accuracy of exposure results by automatically calibrating exposure results based on the amount of light exposure. This feature further contributes to the accurate and consistent exposure results that is by using a licensed technology from the University of California San Diego. I7A is indeed a remarkable and reliable wafer stepper that sets a new standard in wafer stepper performance. Combining ultra-fast scanning, superior alignment accuracy, high resolution and exposure consistency, NIKON i7A provides manufacturers the reliable and consistent performance they need from an advanced lithography model.
