Used NIKON NSR 2205 G8 #152212 for sale

NIKON NSR 2205 G8 is a wafer stepper that is part of NIKON STEP Wafer Stepper Series. It is used in the photolithography stage of semiconductor manufacturing and allows for the transfer of circuitry patterns from reticles onto the photoresist on the silicon or glass wafers. NSR 2205 G8 is capable of high optical performance, accuracy, and resolution. NIKON NSR 2205 G8 has an optical equipment with five optical components, including a Field Lens, Step Lens, Projector Lens, Image Scanning Assembly, and a Reticle. The Field Lens corrects aberration that arises from the difference between the object and image side. The Step Lens is used to transfer the circuit pattern of the reticle across multiple positions. The Projector Lens projects the reticle image onto a large medium size surface. It also has a large magnification power that allows for high pinpoint accuracy. The Image Scanning Assembly scans wafers at ultra-high speeds with superior accuracy that is about fifteen times faster than the shutter transfer. Lastly, the Reticle is used in reverse projection imaging to ensure accurate alignment. NSR 2205 G8 also has several features that ensure high precision and accuracy. Its Ultra Precision Reticle Alignment uses a newly developed differential auto-alignment system (DAAS), which enables it to measure the height of the reticle surface and make corrections before aligning the moveable stage to maximize accuracy. It also has Auto Autofocus Levelling, which is used to adjust the focus by measuring the displacement of the wafer surface and making any necessary corrections before exposure. This allows for high resolution imaging with superior accuracy. NIKON NSR 2205 G8 also offers a highly optimized light source that helps minimize long-term drift in illumination uniformity for the most innovative imaging performance. It also has an energy-saving cooling unit that maximizes energy efficiency. This machine uses a thermoelectric cooling unit and a heat exchanger, which enables a rapid temperature rise, so it requires less energy than conventional cooling systems. NSR 2205 G8 also offers a user-friendly VARI-Exposure interface that helps to reduce non-uniformity due to external influences such as temperature, humidity, and ambient light fluctuations. This ensures that the image quality remains stable, even in extreme environments. Additionally, it has a powerful pattern recognition tool that can recognize up to twenty-four different patterns simultaneously, and it supports a variety of reticles. Overall, NIKON NSR 2205 G8 wafer stepper is a reliable, accurate device that is designed to handle a variety of wafer stepper applications with superior performance, accuracy, and resolution. Its advanced features offer reliable, repeatable imaging performance and efficient, energy saving operation.
