Used NIKON NSR S204B #293678915 for sale

NIKON NSR S204B is a wafer stepper designed for precision lithography used in the semiconductor industry. It is part of NIKON NSR series and is one of the most reliable and advanced systems available. The S204B uses a human machine interface for easy operation, and includes an array of high-performance optics, automated control, and motion control systems. The objective lens for the S204B is NIKON AIMEX VXR270, a large-aperture high-resolution aberration-corrected objective lens. It has an NA of 0.35 and a full-field magnification of 3x. This allows it to achieve precision micron/sub-micron lithography resolutions as well as high throughput. The lens also utilizes a linear motor-based drive equipment for smooth, vibration-free operation. The S204B also features NIKON proprietary MMC-5000E control platform, allowing for automated and precise control of the system. This control platform supports a wide range of control functions including exposure time, resolution, process parameters, reticle movement and alignment, and wafer stage accuracy. It features an intuitive graphical user interface, which makes operation easy and efficient. In addition to its advanced optics and controls, NIKON NSR-S204B is equipped with a range of wafer handling capabilities. It is equipped with an electro-magnetic chuck for carrying wafers up to 200mm in diameter, as well as a cassette loader for automatically loading/unloading wafer cassettes. This versatile unit also includes a selection of accessories for pre-processing and post-processing operations. This includes an automatic wafer mapper for checking wafer distortion (WRA), an up-down motion table for mapping and registration, and a stepper control table for laser alignment control. Overall, NSR S 204 B is a powerful and reliable wafer-stepper machine that provides precision micron/sub-micron lithography resolutions, automated wafer handling, and intuitive interfacing. It is ideal for applications ranging from microelectronics, to medical devices, to opto-electronics, and more.
