Used NIKON NSR S204B #9254164 for sale

NIKON NSR S204B Wafer Stepper is a photolithography machine designed for semiconductor wafer processing. It is designed for chip level applications, such as creating transistors, capacitors, and other components on a semiconductor wafer. NIKON NSR-S204B is a high resolution, high throughput machine. It features a 4-inch planar field-of-view and a design that allows it to maintain a linewidth resolution of 0.17 microns. At the core of NSR S 204 B is a high efficiency excimer laser that is used to create extremely precise patterning on the wafer surface. The laser's spot size is only 0.3 microns wide. This allows it to create extremely small and intricate patterns which are then transferred onto the wafer surface. The patterns can be either predetermined or created on the fly, allowing for maximum flexibility in design. The stepper is built with advanced optical imaging technology, allowing it to accurately transfer patterns onto the wafer surface with a high degree of accuracy. The imaging equipment uses a combination of both chromascopic and interference patterning. This allows it to accurately transfer even the most complex designs onto the wafer with little to no distortion. Additionally, the system is designed to optimize the imaging field-of-view, meaning it is more efficient in producing patterns on the wafer with less time and effort. NIKON NSR-S 204 B also comes with a range of features that make it user friendly and reliable. These features include an intuitive software interface, a low noise chamber, and an automated alignment unit. The software allows users to compress multiple complex images into a single file and simulate the transfers. The low noise chamber helps to reduce cross talk while the alignment machine helps to compensate for any misalignment issues. Overall, NSR-S 204 B is an effective and reliable tool for performing high resolution and precise lithography on semiconductor wafers. Its powerful optics and user friendly features make it a versatile tool for both beginners and experts alike. With its advanced optical imaging capabilities, NSR-S204B is well suited to produce intricate patterns on semiconductor wafers with a high degree of accuracy and speed.
