Used NIKON NSR 2205 EX14C #293591967 for sale

NIKON NSR 2205 EX14C is a state-of-the-art wafer stepper used in the production of integrated circuits. The wafer stepper provides high-quality photolithography with its advanced features and automation. It incorporates a unique digital servo-motor equipment, which ensures precise and accurate movement of the stage. The digital servo-motor system includes two linear axes of motion and one rotational axis, allowing for precise and accurate alignment of the given pattern. The stepper uses laser alignment unit to ensure accurate alignment with the printing area centers. The stepper machine also has a 4-axis geometric correction tool, which allows for the correction of pattern distortion due to process related motor and stage variances. This asset also enables multiple groups of patterns to be printed at once, as well as a step-and-repeat recording method that can repeat the same pattern multiple times. It brings increased production capacity and repeatability. The stepper also has a low vibration model that minimizes ripple and noise. NIKON NSR-2205EX14C's laser alignment equipment includes two laser heads and two beams, which enables fast setup and improved throughput. The placement accuracy can remain unchanged throughout the entire run, even when the wafer size changes. Furthermore, the stepper is equipped with a high NA (numerical aperture) illumination system that uses a digital image light source and can be used for both oblique and reverse imaging. NSR-2205 EX14C is a reliable, high-precision stepper unit that meets the high demands of today's semiconductor fabrication processes. It utilizes NIKON advanced optical processing technologies and meticulous housing design, allowing for the precise photolithography needed in these processes. The stepper is designed for high-volume production, utilizing automated control and minimal maintenance for maximum throughput and minimum downtime.
