Used NIKON NSR G3A #9194239 for sale

NIKON NSR G3A (a wafer stepper) is a highly advanced lithography equipment developed for research laboratories and wafer fabrication. It utilizes advanced technology to automatically align and expose photomasks and reticles on wafers, which are then used for producing integrated circuits (ICs). NSR G3A has a stepper for transferring the pattern from a reticle onto a wafer plane directly. It has a high-resolution laser optical head that can reduce the scanning size to submicron level, as well as a high accuracy, high speed stage system with a stage tracking sensor for mask-to-wafer alignment and stable reception. Furthermore, the unit is equipped with an image reduction machine, which adjusts the reduced magnification of the pattern. The tool employs a super high-speed one step movement for accurate alignment and fast exposure. Additionally, a simple standby command enables the asset to start at anytime, resuming from its last exposure position within two minutes. NIKON NSR G3A also uses a KLA2D image processing model for fully automated alignment and patten analysis. The equipment automatically recognizes the wafer edge and overlaying alignment patterns from multiple exposure sequences to check the exact exposure sizes. The advanced design of NSR G3A ensures its low coherence illumination system is capable of patterning isolated related structures with a width of 1 micron or less. Additionally, its process control software enables the user to perform calibration tests and create and edit exposure programs. This unit is also equipped with a motorized mask-leveling stage that quickly adjusts astigmatism without changing focus. In conclusion, NIKON NSR G3A is an ideal choice for research laboratories and wafer fabrication. Its high resolution laser optical head, motorized mask-leveling stage, and simple standby command combine to provide an efficient lithography machine capable of placing an accurate and precise patterns onto wafers. As a result, this tool is an excellent choice for creating integrated circuits.
