Used NIKON KDP1640EHE #293668739 for sale

NIKON KDP1640EHE wafer stepper is a next-generation equipment that is designed to provide high resolution imaging and lithography performance for advanced semiconductor device production. It is configured with a NIKON field emission gun scanning electron microscope (FEG-SEM) and direct exposure technology that offers low-distortion, high-speed digital imaging. KDP1640EHE has a five-axis bridge-type motion stage isolation system with a high-speed orthogonal scan that ensures repeatable and stable placement accuracy and step and repeat performance. It is designed to accommodate up to four 6-inch wafers at a time, and can handle up to 20 mm thick wafers with a minimal strip-width of 0.2 μm. This unit also includes a high-speed reticle exchange capability with a low-distortion mounted reticle combiner for improved registration accuracy and reduced alignment time. The machine's lens control tool features high accuracy four-axis alignment and highly precise step and repeat capability that offers superb image processing and lithography performance. It features an automated image centering asset that automatically centers the wafer to provide the best exposure, and a powerful mask pattern editor, allowing operators to quickly create intricate exposure patterns. NIKON KDP1640EHE's motorized reticle stage offers up to +/-1 μm precision shifts to maximize the throughput with its motorized reticle load and unload capability. The model's automatic alignment functions ensure a shiftless high-speed scan exposure, allowing the operator to focus on other tasks. Furthermore, it is equipped with a focus monitor to monitor the focus range of each stepper shot. In addition to providing the accuracy and precision expected of a high-end wafer stepper, KDP1640EHE also offers an intuitive graphical user interface (GUI) and easy-to-use data control functions. Features like imaging conditions, programmable lens control settings, and pattern editing functions are accessible through the GUI, and the included self-test and setup functions offer detailed information regarding equipment performance and capabilities. The control console also allows for a quick start-up process with an 8-inch touchscreen interface and a large format, ergonomic keyboard. Overall, NIKON KDP1640EHE is an extremely reliable and user-friendly system that offers operators the accuracy and speed needed for sophisticated semiconductor device production. Its automated alignment, comprehensive image editing, and improved focus monitoring tools make it an ideal unit for large-scale device manufacturing and research applications.
