Used NIKON i9 #139030 for sale

NIKON i9 is a high-precision, top-of-the-line photolithography wafer stepper. It is used to transfer patterns from photomask to a semiconductor wafer, the main component in integrated circuits. The stepper operates on a synchronized mechanism which brings high precision and repeatability in patterns transfer. NIKON I 9 is equipped with a state-of-the-art immersion lens and advanced set of illumination optics. The usage of immersion media such as fluid or gasses allows for high resolution and superior imaging performance. It has a large lens numerical aperture equipment, allowing high resolution printing and overlay accuracy while providing excellent depth of field. The integrated metrology system, based on laser interferometry, allows the user to measure finally printed patterns in-situ on the stepper, without the need to remove the wafer from the machine. This enables quick and easy detection of wafer-level defects that can occur during the process. The stepper offers sample support, which is composed of two stages, the substrate stage and the mask stage. The substrate and mask stages are equipped with optical sensors for detecting movement, and are linked and controlled by a complex network of linear motors and precision encoders, providing extremely precise and repeatable movement. I9 also features an auto focus unit which automatically determines the plane of the wafer and keeps it in focus. This eliminates the need for manual adjustment and helps improve production throughput. I 9 is run by an intuitive and user friendly PC based control machine which includes numerous features such as fine tuning of parameters, real time monitoring of the post-exposure tool and error detection capabilities. High durability and long life performance has been ensured through numerous safety protocols and testing procedures. This ensures reliable and consistent performance over a long period of time. Overall, NIKON i9 is an advanced, cutting-edge wafer stepper with superior imaging performance, real-time monitoring capabilities, automatic focus and integrated metrology capabilities. It is an invaluable tool for precision production of integrated circuits, offering extreme accuracy and repeatability.
