Used NIKON i7 #9144951 for sale

NIKON i7 is an advanced and highly precise wafer stepper which is used primarily in semiconductor manufacturing. It can store up to 9,000 recipes and is compatible with a variety of mask sizes with a maximum mask size of 630mm x 544mm. NIKON I 7 utilizes a new-generation Tilt and Shift Lens Equipment, which can accurately reduce the amount of residual image shift (RIS) on the wafers produced by a fraction. With a resolution of 0.5µm, this model is capable of producing excellent-quality wafers with minimal particle contamination. I7 is also equipped with advanced Exposure Control Technology (ECT), which helps to maintain consistent exposure of the wafer to ultraviolet light during production. ECT compensates for autoFocus, autoZoom, shutter speed, iris opening, and wavelength settings to ensure a consistent exposure process across all steps. I 7 also features a Full IC Cassette Handler, which allows for the automated feeding and transfer of ICs and wafers between NIKON i7 and other stages in the device fabrication process. This system ensures faster, easier and more efficient alignment, loading, and unloading of wafers as well as improved productivity. NIKON I 7 is also equipped with an advanced Image Stabilization Unit (ISS), which helps to reduce the amount of "bump" on the wafer caused by misalignment between the wafer and the optics. ISS works by measuring displacement, vibration, and other motion in wafer movement and then compensating with its advanced image stabilization machine. I7 wafer stepper is an essential part of any semiconductor production line, as it provides a highly precise and accurate architecture for the production of wafers. Its advanced exposure control technology, tilt and shift lens tool, full IC cassette handler, and image stabilization asset allows for efficient and consistent production of devices with minimal particle contamination.
