Used NIKON NSR 204B #9350967 for sale

NIKON NSR 204B is a semiconductor lithography tool used in the manufacturing of integrated circuits and related products. It is used to transfer patterns onto wafers of material, allowing for the definition of electronic characteristics in the integrated circuits. NIKON NSR-204B is based on NIKON NSR-S203B Step and Scan equipment. It is an advanced imaging system that employs a two-dimensional (2D) alignment lens and the illumination unit to image the mask patterns on the reticle through an optical machine. The instrument is an improved version of NIKON S203B, with improved resolution, alignment accuracy, and throughput. It has a higher throughput compared to NIKON S203B, which allows for a faster processing time when manufacturing integrated circuits. NSR 204B tool consists of the scanner, the Alignment and Illumination (A&I) head, the Reticle Stage and Reticle Stage and optics. The scanner has a standard optical layout, composed of a reticle, a reticle alignment lens, a reticle position monitor, a wavelength-world scanning CRT, and a projection lens. The scanner can handle multiple reticles, allowing for multiple exposures at once. The Alignment and Illumination (A&I) head contains a mirror, a lens, and a number of light sources used to project and illuminate the reticle patterns. The lens is used to focus the light onto the reticle in a specific pattern. The mirror can tilt for specific illumination angles, which ensures the accuracy of the pattern. The Reticle Stage is used for the secure placement and accurate alignment of the reticles on the projection lens. The position of the reticles is monitored and controlled using a laser asset. The optics of NSR-204B includes an aberration-corrected projection lens and a field flattening prism. The projection lens is used to image the reticle patterns onto the wafer. The field flattening prism is used to flatten the field to eliminate any aberrations from the imaging process. NIKON NSR 204B can handle a variety of wafer sizes, from 6 inch to 8 inch in diameter. It also has a low-temperature environment, allowing for superior image integrity and processing speeds. Overall, NIKON NSR-204B is a high-precision lithography tool that can handle a variety of wafer sizes and provides excellent resolution, throughput, and alignment accuracy. It is an ideal choice for the production of integrated circuits and other related components.
