Karl Suss mask aligners (manufactured by SUSS MicroTec) are industry-standard photolithography tools used to transfer geometric patterns from a photomask to a photosensitive substrate (like a silicon wafer). They are widely deployed in semiconductor research, MEMS fabrication, and micro-optics. Key Common Features • Exposure Modes: Most models support multiple exposure contacts, including soft contact, hard contact, vacuum contact, and proximity modes. • Wavelength Capabilities: They utilize UV broadband light, commonly optimized for i-line (365 nm) and g-line (436 nm) photoresists. • Precision Control: Microscopic alignment stages utilize X, Y, and Theta (θ) mechanical adjustments to match wafer alignment marks symmetrically with mask features BUYER IS RESPONSIBLE FOR REMOVAL OF ITEMS INCLUDING ALL PACKING, LOADING, HAULING, AND SHIPPING.
