Used ULTRATECH 1000 #9004070 for sale

ULTRATECH 1000 wafer stepper is designed for high resolution photolithography. It utilizes a 1-micron theta stage, which gives user the capability of extremely accurate alignment and placement of micro-miniature patterns on wafers. 1000 has a highly sophisticated optical equipment with a dual-camera imaging system and a unique brightness control that can automatically adjust the exposure level of each photo layer. ULTRATECH 1000 is equipped with an ultra-fast resonant scanner that can cycle quickly between different exposure fields on the wafer. It also features an advanced patent-pending image transformation algorithm for increased accuracy of registration of wafer images. This algorithm automatically compensates for distortions due to slight variations in wafer surface or temperature during the exposure process. Additionally, the stepper has a patented TurboChromatic dual-wavelength LED light source for varying exposure settings. The stepper is also equipped with several other features that contribute to its high accuracy, such as a 4-axis scanning head, variable depth scanners, and a patented Advanced Zone Scanning (AZS) feature. The AZS function gives users the capability of scanning different zones on a wafer, thus increasing the scope of exposure. Additionally, the unit comes with a built-in calibration unit that enables the user to regularly adjust the exposure levels and settings. 1000 is also suitable for use in production environments with its unique built-in high-reliability synchronization of exposure fields. ULTRATECH 1000 wafer stepper has several user-friendly features, such as Windows-based video graphic operations software and a graphic user interface. The interface makes it easy to control the exposure settings and can operate with a single point or multiple point exposure. Additionally, the stepper has a proprietary Synchronized Spreading Machine that helps to reduce the whitewash effect due to overlapping exposures. Overall, 1000 wafer stepper is a sophisticated yet user-friendly machine that enables high precision photolithographic processes. With its dual-camera imaging tool, AZS feature, and numerous other features, ULTRATECH 1000 is an enterprise-grade wafer stepper offering superior reproducibility and resolution for prototyping, production, and wafer-level packaging applications.
