NIKON NSR 4425i is a state-of-the-art wafer stepper designed for semiconductor processing. The stepper has two main components, a stepper head and a dual-stage wafer handler. The stepper head is equipped with a large-field, high-numerical-aperture NIKON TIRF optics system, allowing it to achieve an extremely high level of resolution, with a minimum line/space of 0.30 μm (1.22 mil). The dual-stage wafer handler is designed for precise alignment and handling of up to 6-inch diameter 300mm wafers. The stepper is also equipped with high level automation features, including automatic alignment and focus adjustment, precise wafer locating, and automated wafer movement that eliminate manual handling. These features allow for faster and more precise processing of wafers. This makes it ideal for wafer processing tasks such as lithography, photomasking, and metrology. NIKON NSR-4425I is equipped with an advanced light source, featuring a variable-wavelength, laser-illuminated discharge lamp. This allows for greater flexibility and accuracy when exposing a wafer to a light source. The lamp features a wide dynamic range and constant chromaticity, allowing for precise photo-lithography. The stepper is also equipped with an advanced control system, which allows the user to monitor the wafer processing operations in real-time and to adjust parameters as needed. It features a user-friendly interface, providing simple, intuitive access to monitoring and control functions. It also boasts a variety of advanced features, such as pattern recognition and edge detection. The stepper is built on a sturdy and reliable frame, making it well suited for long hours of operation in harsh environments. Its sturdy, vibration-dampening design ensures that the critical alignment and focus parameters remain consistent over long periods of time. It also has an adjustable beam aperture, making it suitable for a wide range of applications. NSR 4425 I is a professional-grade wafer stepper capable of delivering a high level of speed, accuracy, and precision when handling and processing wafers. With its advanced automation and control features, it can be used to quickly and accurately process wafers, making it a great choice for semiconductor manufacturing and research applications.
