Used NIKON G7 #293793324 for sale

NIKON G7 is a high-end optical lithography stepper used for the manufacture of semiconductor devices. It is equipped with advanced lithography optics, aligning accuracy, a precision XY stage, and a high-speed wafer transport equipment. NIKON G 7 is equipped with a 6M pixel CCD, a powerful 100W mercury lamp, and a high numerical aperture (NA) of 0.7. The system can capture finer features and provide the highest throughput in the most demanding semiconductor production wafer configurations. G7 has two exposure modes: the beam-splitting mode, in which the focused beam is used both for exposure and alignment, and the single-beam mode, in which only the exposure is used. Both modes use a unique exposure strategy that combines low exposure dose and high productivity. G 7 features a unique XY stage design that offers very high precision in all axes. It is capable of precise alignment accuracy of 2.5 µm even at high stages speeds. Additionally, the edges of the field of view are round and continuous, providing an improved image quality and better wafer coverage. The scanning unit features a large scan area that enables maximum field overlap and uniform uniformity throughout the entire wafer. The scanning motion is further improved by three highly advanced sub-scanning systems: two to drive the stage in three axes, and one to do the profiling. The wafer transport machine of NIKON G7 features high speed wafer clamping and unclamping, and high-speed wafer transfers. All drives are linear, eliminating any vibrations, noise and wear. The drive motors are capable of providing up to 8 motor phases to ensure speeds up to 500mm/s. NIKON G 7 is fitted with a full-fledged job execution tool that can easily integrate and operate with third party software and control systems. The asset also supports touch screen operation and integration of routine tests such as critical dimension and process window measurements. Overall, G7 is a powerful wafer stepper that offers a high level of precision and throughput for advanced semiconductor device manufacturing. With its unique features, it is a great choice for any production line.
