Used ASML Twinscan AT 1200B #293663069 for sale

ASML Twinscan AT 1200B is a high precision wafer stepper used for photolithography. It is designed to provide high resolution pattern transfer onto substrates such as semiconductor wafers, while maintaining the product's dimensional accuracy. Twinscan AT 1200B utilizes high precision stepper motors for motion control, enabling it to achieve positional accuracy of microns. This equipment features high resolution optical components, including a zoom magnifier, telecentric optics, projection lenses, an infrared alignment system, and a variable numerical aperture. All of these elements combined provide a high precision imaging unit. ASML Twinscan AT 1200B is capable of handling substrates up to twelve inches in diameter. It features a stepper arm with a variable speed to enable rotation of the substrate and alignment of the exposed surface. The stepper arm is connected to a carrier that slides horizontally across the substrate table, allowing for precise and fast positioning. Twinscan AT 1200B also offers an automated alignment machine, which uses optical sensors to track the substrate's location on the table. This tool allows for faster and more accurate adjustment of the components. The stepper also features an optional leveling asset, which measures the substrate's surface at various sites and adjusts its height to ensure accuracy. In addition to its precision components and alignment model, ASML Twinscan AT 1200B has both a light masker and process control unit. The light masker is used to control exposure levels and focus devices, while the process control unit permits the user to adjust recipe parameters such as illumination levels and exposure times. Twinscan AT 1200B offers a wide range of capabilities for photolithography. Its high precision imaging equipment and control components provide accurate and reliable pattern transfer, while its automated alignment and optional leveler ensure reliable performance. Combined with its compatibility with numerous substrates, ASML Twinscan AT 1200B is an excellent choice for those needing a precise and reliable wafer stepper.
