Used NIKON G4D #9144947 for sale

NIKON G4D is a wafer stepper, a type of lithography tool used in the semiconductor industry. It is capable of producing semiconductor devices with a high degree of accuracy and precision. It features an advanced optical equipment, as well as precision x-y alignment capabilities, and state-of-the-art computer control. With its advanced optical components and highly accurate alignment, G4D is able to produce extremely high-resolution structures and features as small as 0.2 micron spacing in both x and y axes. NIKON G4D's optical system contains a high numerical aperture Scanning Numerical Aperture (SNAP) unit and a 12mm Field Emitter Array (FEA) array. The SNAP machine consists of a movable mirror assembly, a precise focusing diaphragm, and a highly sensitive image array. Its advanced optics are able to produce clear and detailed images that cover a wide and customizable array of features, enabling it to effectively write patterned masks onto semiconductor wafers. G4D's state-of-the-art computer control uses a synchronous step-and-repeat controller to ensure that each mask is properly positioned prior to exposure. This tool is also able to manipulate complex, multi-level scans in order to produce a range of results, which makes it a highly versatile tool. Furthermore, the unit also features an internal Quality Control Asset (QCS) to monitor and adjust the exposure process. NIKON G4D also has a wide range of features, allowing for flexibility in lithography. It has a high-speed contour programming model for easy patterning, as well as a range of exposure sources that include laser and electron beams. It also offers built-in calibration, as well as a range of temperature and film control settings. Overall, G4D is an extremely reliable and precise lithography tool for producing high-resolution semiconductor devices. Its advanced optical equipment, highly accurate alignment capabilities, and state-of-the-art computer control make it well suited for cutting-edge production requirements.
