Witryna30 paź 2024 · Other changes may include alignment and leveling sensors, to enable optimal process control and facilitate overlay matching to the immersion scanner NXT:2000i. In commercial fabs EUV lithography is used for critical layers while lower cost immersion scanners are used for the majority of wafer processing making … The greatest limitation on the ability to produce increasingly finer lines on the surface of the wafer has been the wavelength of the light used in the exposure system. As the required lines have become narrower and narrower, illumination sources producing light with progressively shorter wavelengths have been put into service in steppers and scanners. An alternative to conventional light bas…

NSR-S635E ArF immersion scanner - Nikon Precision
WitrynaThis was followed by the evolutionary NSR-S621D, S622D, S630D, and S631E immersion scanners for applications down to the 7 nm node and beyond. It is real-world, on-product performance that is vital to chipmakers. The NSR-S635E is the industry’s most advanced scanner for aggressive multiple patterning processes. WitrynaNikon offers the industry-leading DUV NSR-S322F ArF and NSR-S220D KrF scanners, which utilize the innovative Streamlign platform to deliver world-class performance for critical non-immersion layers. The successful combination of the Stream Alignment and Five-Eye FIA systems enables scanner throughput ≥ 230 wafers per hour.
