Used ULTRATECH 1500 #9174373 for sale

ULTRATECH 1500 is a state-of-the-art wafer stepper used in chip fabrication. It is used to transfer patterns from photomasks to wafers, as well as performing other exposure- and etch-related steps in the lithography process. 1500 offers a wide scanning speed range of 0.25mm/sec to 250 mm/sec, which is ideal for high throughput and short exposure time. Each scan is controlled by micro-stepping motors that provide precise and repeatable positioning, along with a large working area of 420mm x 485mm. The scanner also has an automated wafer alignment system to ensure accurate placement of the wafer on the machine and an automatic wafer handling system which makes it easy to move wafers between steps. The unit includes both advanced alignment and correction functions to ensure high accuracy, which is essential for critical exposure and lithography processes. Advanced correction features such as scan-line adjustment and preset software algorithms allow the machine to self-calibrate and fine-tune parameters for optimal performance. ULTRATECH 1500 also offers advanced backside imaging capabilities, including in-situ flatness, alignment, and exposure panning. 1500 is highly efficient, reliable, and user-friendly, and its advanced features ensure fast turnaround time and high yields. It's also equipped with an inert ambient environment and a nitrogen-purged enclosure to protect sensitive components from dust, chemicals, and other debris. Overall, ULTRATECH 1500 is a top-of-the-line wafer stepper that offers state-of-the-art features and performance. Its robust design, advanced functions, and reliable operation make it the ideal choice for chip fabrication, especially when time and accuracy are top priority.
