Used NIKON NSR 1755 G7A #293610524 for sale

NIKON NSR 1755 G7A is a semi-auto wafer stepper specially designed for precise lithography processing in the semiconductor industry. It is one of the most advanced and reliable steppers in its class, able to successfully process advanced device layers with a resolution down to 0.26 μm. NIKON NSR-1755G7A is driven by a 4,500 W high-power ArF excimer laser light source, resulting in excellent image quality and uniformity, even at the highest speed. It features an integrated equipment of advanced lithography components capable of processing various types of substrates, including both cut and uncut wafers. With an impressive patterning rate of 86,000 die per hour and an extended alignment accuracy of 0.5 μm, NSR-1755 G7A is well suited for high-density and high-volume manufacturing operations. The machine is equipped with a NIKON Vector Aligner (NVA) and a two-stage system capable of optimizing the alignment of patterns on multiple layers to achieve the highest production yield. The NVA uses Deep Ultraviolet (DUV) laser microscopy for quick and precise laser alignment at the substrate level, allowing for accurate detections of even the most challenging alignment and positioning issues. The machine also has a built-in wavefront monitor which helps control wavefront aberration to maintain excellent imaging across a wide range of exposure settings. As an additional feature, NSR 1755 G7A includes an integrated resist dispersal unit and an accurate micrometer-derived nozzle that ensures uniform dispersion of resists. This feature ensures proper coating of the substrate while preventing any cross contamination of the resist, making this machine highly accurate and efficient. NSR-1755G7A is designed with a compact and easy-to-maintain architecture, making it one of the most cost-effective solutions for lithography processing. The machine comprises of an air-cooled spotlight machine, simplifying its setup and maintenance, while its body is designed with a fade-free polycarbonate surface, with shielding to protect operators while they work. In short, NIKON NSR-1755 G7A is a semi-auto wafer stepper that is capable of providing precise lithography processing for advanced device layers with resolution down to 0.26 μm. The machine is equipped with an integrated tool of advanced lithography components, a 4,500 W high-power ArF excimer laser light source, an accurate micrometer-derived nozzle for resist dispersion, and a NIKON Vector Aligner to ensure precise alignment of patterns. It is an efficient and cost-effective machine, making it an ideal choice for high-density and high-volume lithography processing operations.
