Used NIKON G6 #293793323 for sale

NIKON G6 is a high precision wafer stepper manufactured by NIKON Instruments Inc. It is capable of accurately imaging a wide range of wafer sizes and die configurations with high throughput throughputs and low line widths. Designed to meet the demands of the semiconductor industry, NIKON G 6 also boasts superior linearity of motion and image-quality metrics. G6 is a four-axis equipment that is composed of two scanning stages, a wafer stage, and a detector stage. The scanning stages are responsible for accurate positioning the wafer relative to the detector as determined by the control system. The wafer stage is composed of a vacuum-sealed platform that is driven by an air bearing unit and a fine-pitch lead screw. The detector stage is driven by a direct-drive stepper motor that aligns a cellular imaging device to the wafer stage. G 6 is capable of imaging wafers up to 8 inches in diameter. The machine has an XY resolution of 0.01 µm and a Z resolution of 0.001 µm, with a Z wafer-to-detector clearance of 5 mm. Additionally, NIKON G6 has a global flatness of 0.5 µm, making it suitable for high-quantity, high-accuracy imaging. NIKON G 6 also features an extensive list of integrated optics, including a vertical Fourier Transform Lens and a dual-line CCD sensor. G6 also has a number of advanced features and optional components that make it ideal for precision alignment and imaging. These features include an auto-collimation tool, a computerized 1D exposure control capabilities, and programmable laser alignment and microscope capabilities. Other advanced features include an integrated high-speed, motorized XY stage, register markings for image alignment, and fiducial marks for repeatable, accurate scanning. In addition, G 6 is capable of handling wafers up to 8" in diameter and also possesses a coupling asset for critical alignment between wafers and detectors. It also has the ability to control exposure times and image shutter speed, and to reduce jitter and image distortions. Finally, NIKON G6 offers an Ethernet communication interface for remote control and monitoring. NIKON G 6 is an ideal wafer stepper for the semiconductor industry, as it offers superior image-quality metrics, precision linearity of motion, and a wide range of support features. With its various components and advanced features, G6 is capable of producing accurate, high-quality wafer images with excellent throughput.
