The Twinscan NXT:2050i is a deep ultraviolet immersion scanner for high-volume manufacturing at advanced logic and memory nodes. The Twinscan NXT:2050i uses 193 nm ArF immersion optics and an advanced wafer stage design to drive thousands of wafers per day through critical patterning steps.[1]
How it works
The Twinscan NXT 2050 i uses 193 nm argon-fluoride (ArF) immersion optics. A thin layer of water is introduced between the final lens and the wafer to increase the numerical aperture, enabling finer resolution than dry DUV systems. The system employs a dual-stage wafer stage that allows one wafer to be aligned while another is being exposed, reducing idle time. The NXT:2050i is positioned for throughput ranges similar to typical DUV immersion systems, which can exceed 250 wafers per hour under volume conditions.[1][3]
