Used NIKON NSR S206 #293817851 for sale

NIKON NSR S206 is a wafer stepper used primarily for photolithographic process technology used in microfabrication. It is designed to image a photoresist coating over a semiconductor substrate through a process called "exposure". This stepper has two exposure systems, one of which utilizes a mercury halide lamp and the other, an LED array. According to requirements, it is possible to change the illumination source from exposure point of view. This equipment allows for the stepper to perform with higher speed and ensures high precision patterning with a resolution up to 0.25 micrometers. The stepper allows for a wide variety of photomasks and resists to be used. This includes positive, negative, and sable tone resists. NSR S206 is also capable of the use of various substrates, including glass substrates, wafer substrates such as Silicon, Ge, GaAs, and InP. It can also accommodate medium-sized plates such as quartz. The stepper allows for high precision uniformity in images over large fields without the need for stitching or manual retouching. Its automatic stitching feature allows for large fields to be divided into smaller pieces, exposing them, and then stitching them together. In addition, NIKON NSR S206 is capable of exposing large stepped fields. The wafer's surface is kept clean with the built-in laser cleaner, which also helps with images' fidelity. Furthermore, its auto focus and exposure control features deliver extremely fine micron patterns. Its software allows for sophisticated image optimization and also blends faster imaging times with superb NA (Numerical Aperture) pulling power. The stepper comes with an intuitive graphical user interface (GUI) and can be integrated with several photomask producing techniques. Overall, NSR S206 is an advanced stepper that can offer impressive throughput and resolution. It is designed to maximize efficiency and repeatability for advanced semiconductor processes.
