Used NIKON NSR S204B #293594683 for sale

NIKON NSR S204B is an immersion scanner wafer stepper designed to fulfill advanced ultra-small device and microelectronics requirements. It has an advanced alignment equipment and the capability of handling large substrates and accurate movement up to 200mm (7.87 inches) while providing high resolution and uniform focus. NIKON NSR-S204B has a large substrate size of up to 200mm, a compact size, and an end station with a stage that can move four wafers/reticles simultaneously. It also has an improved stage design for wafer handling. The wafer stepper design is for finer alignment accuracy with a single source system with small field stigmatic imaging optics. The optical zoom unit has a wide range of views from 0.60x to 0.80x. It also has a long working distance, a vibration-free scanning machine, and a wafer handling tool for accurate control. NSR S 204 B asset uses an integrated stigmatic imaging optic lens with laser interference pattern (LIP) projection illumination and an automatic reticle alignment model. It has a long working distance and is capable of high resolution imaging capable of handling fine line patterns. The equipment can scan multiple shot fields of up to 300mm (11.8 inches) in height and a maximum of 2000mm (78.7 inches) in total length. NIKON NSR-S 204 B provides low temperature exposure down to 25 degree Celsius (77 Fahrenheit) and is capable of achieving uniform resist thickness with advanced resist heating control. The wafer stepper is extremely reliable and offers high yield rate ( 95% ) and low downtime. The system also has high throughput with a maximum throughput of 4000 (8") wafers/ hour. In addition, it has a high productivity with its high resolution, high accuracy, and high repeatability with its ability to handle fine line patterns. Overall, NSR-S204B wafer stepper is highly reliable, high throughput, and provides high accuracy. It is a perfect choice for advanced ultra-small device fabrication and microelectronics applications. With its high resolution, large substrate size, and small field stigmatic imaging optics NSR S204B can provide superior imaging results and unparalleled repeatability.
