Used NIKON i8 #9155056 for sale

NIKON i8 is a state-of-the-art lithography stepper that is used in a variety of applications ranging from semiconductor fabrication to medical device manufacturing. It is a high-precision tool that uses projected light imaging to precisely create patterns on substrates based on computer-generated designs. NIKON I 8 was the first commercial lithography stepper and remains the flagship of NIKON lithography tools. I8 consists of several components. First, it has an illumination equipment that relies on an ultrahigh-pressure mercury lamp as its light source. This light source is positioned outside the system, partially for enhanced safety and reliability. The centered light source is gold-plated to improve reflectivity. The slit size and shape can also be adjusted with internal adjustments and an improved dark field response. The projection unit has an aperture size of 25mm, and can produce large exposure fields up to an impressive 20mm square. It also features enhanced vertical alignment (VA) resolution of 0.51 mJ/cm2, or 45-nm half-pitch resolution, with a resulting feature size of 1.2um for dense lines and spaces down to 0.1um in small-geometry devices. Equipped with a robust motor or actuator, it offers faster stepping-motor operation and greater drive cycle flexibility, resulting in superior wafer to wafer alignment accuracy. The projection machine also includes an original low-angle scanning tool for mapping large patterns over larger areas for improved surface coverage. I 8 also features a variety of software tools to optimize lithography processes, including a hierarchical validation checker, a fault detection asset, and an auto-exposure adjustment model. Additionally, its innovative Dicing Output (DOC) equipment allows users to perform single-wafer patterning with a single exposure. Its powerful software is highly intuitive, allowing users to easily modify exposures, modify photo techniques, and store and retrieve mask designs. NIKON i8 lithography stepper provides a reliable platform for the efficient creation of complex patterns with incredible accuracy and resolution. With its unique features, powerful software, and performance capabilities, NIKON I 8 is the industry's preferred lithography stepper for many precision applications.
