Used NIKON NSR 1755 G7A #9299965 for sale

NIKON NSR 1755 G7A is a wafer stepper specifically designed for advanced semiconductor processes. It is the most advanced stepper from NIKON, and it is used extensively in the semiconductor industry for both logic and memory device fabrication. NIKON NSR-1755G7A features a dual scanning system for long and short focal lengths. It offers high-fidelity image placement accuracy and stable operation at a variety of scan speeds. Its enhanced optical components offer a higher resolution, improved focus, and precise imaging. The stepper has a maximum field size of 12" x 25" (305mm x635mm), which allows for larger device production. NSR-1755 G7A also offers a range of options to increase throughput. It includes an overcoat mask for printing resists onto wafers, an auto-top tooling device for fast alignment, and a multi-exposure auto-focused system. Other options include a high-speed download CMOS memory option for chip debug and a throughput control driver for fine tuning image placement accuracy. NSR-1755G7A is also part of NIKON advanced Scanning and Modeling (SaM) software suite. This software allows users to analyze and optimize the lithography patterns created by NIKON NSR-1755 G7A. The software is designed to automate wafer alignment, detect process errors, and enhancer edge profiles. Additionally, the software can be used to develop and manage exposure budgets, identify process improvements, and support production planning. Finally, NSR 1755 G7A is equipped with a laser interferometer for positioning accuracy, as well as contactless thickness measurement. The stepper is also capable of wafer loading and unloading, handling flat and uneven substrates. These features make it an ideal tool for high-volume production, as well as for research and development operations.
