Used ASML PAS 5500 / 850C #293817849 for sale

ASML PAS 5500 / 850C is a high precision, high productivity wafer stepper. It has been designed and built to meet the ever-increasing demands of today's semiconductor manufacturers. It is ideal for producing integrated circuits, memory chips, and a variety of other complex wafer-level ICs. The 850C utilizes a proprietary beam lithography equipment, consisting of a projection optics unit and an advanced scanning stage. It uses a low kV, high numerical aperture (NA) lens to provide superior resolution, enabling chip layouts to retain their integrity even during intricate wafer processing. Additionally, a high intensity light source ensures the highest throughput and best imaging results. The 850C utilizes a large number of defect process inspection tools, including aerial image detection, automated failure analysis, and in-die failure inspection. During wafer inspection, the patented "QuadTech" system evaluates the ICs for any process-induced defects, as well as any anomalies associated with the photolithographic process. Additionally, the unit's integrated edge inspection tool enables quick detection of bad edges. In terms of accuracy, the 850C features a displacement encoder with 1nm step resolution and +/-75nm linearity accuracy. The integrated autofocus machine also helps provide optimal wafer flatness, thereby minimizing the impact of either misalignment or wafer surface warp profile. In order to provide robust and long-term performance, the 850C is built with an extended slew rate option, which helps ensure reliable and consistent results, even when processing high-powered chips or difficult layout geometries. Furthermore, its intuitive user interface and process monitoring capabilities allow for easy troubleshooting and tracking of yields. Overall, PAS 5500 / 850C is a reliable, high-end wafer stepper that offers superior resolution, impeccable defect inspection, and long-term performance. It is a perfect device for high-tech industries requiring quality results with shorter turnaround time.
