Used NIKON NSR 1505 G7E #293637485 for sale

NIKON NSR 1505 G7E is a professional-grade wafer stepper used to manufacture precision semiconductor devices. This stepper is capable of patterning the smallest possible structures of any material without damaging the circuit components. It is capable of producing extremely accurate patterns on wafers up to 150mm in diameter with an original step resolution of ± (5 µm) and an overlay accuracy of ± (2.5 µm). NIKON NSR-1505G7E utilizes a unique double-column design, which combines two 86mm columns into one larger, more robust structure. This column arrangement ensures that each step of the patterning process is more stable, accurate, and free from deformation. The stepper also features an improved laser pulse correction equipment, which helps provide accurate patterns on substrates of varying thicknesses. NSR-1505 G7E features a high-resolution scanning system that supports up to 8 mega pixel imaging. This unit provides very high pixel resolutions, up to 120,000 patterns/mm (square pitch) on each wafer. This scanning machine is coupled with an improved two-dimensional stage scanner, which offers superior motion performance and reduces pulsation irregularities. NIKON NSR-1505 G7E's reticle scanner employs auto position recognition and an improved split mirror auto-tracking tool. The combination of these two features provides rapid and accurate alignment measurements across the wafer surface. An advanced wafer loader asset helps feed and manage frequent wafer changes with ease. NSR 1505 G7E also offers a number of advanced process controls. It has the ability to precisely control exposure doses, wafer stage temperature and humidity, as well as operating temperature. Additionally, the stepper can control the focus and beam tilt, making the patterning process even more precise and reliable. NSR-1505G7E is an ideal choice for any demanding high-throughput semiconductor production environments. Its ability to reliably and accurately handle advanced processes makes it a valuable addition to any operations that require top-level performance.
