Used SEMITOOL SRD-470 #293642733 for sale

SEMITOOL SRD-470 is an industry-leading photoresist equipment designed to offer state-of-the-art performance for exposure, development, and clean processes of various semiconductor wafers. Using a combination of reservoir baths and powerful pumps, SRD-470 is able to accurately and precisely deliver small quantities of developer, post-develop rinse, photoresist, and DI water for use in production processes. An automated scrubbing system further amplifies the unit's performance, enabling accurate chemical delivery and wafer cleaning. SEMITOOL SRD-470 is able to work with a variety of wafer geometries, sizes, and materials, from thin microcircuits to large, complex chips. It includes independent rinse baths with a single nozzle for uniform rinse coverage, while its unique pre-mix pulses eliminate splashing and headspace airflow to increase uniformity of rinse delivery. Additionally, SRD-470 boasts an intelligent vision machine that tracks wafer position and movement, increasing both wafer throughput and accuracy. SEMITOOL SRD-470 also offers a full suite of pinpoint control mechanisms designed to offer highly accurate parameters, such as temperature, chemical concentration, flow rate, and other quality control features to ensure precise wafer production. The built-in cyclic timer and archiving of timing profiles allows for improved process repeatability. A host of additional features including installation temperature alarm, wafer jam detector, multiple IO-response with auto-purge, cyclic foot valve, thermal imbalance protection, and end wafer rinse assure superb overall reliability. For fast, efficient work and unparalleled accuracy, SRD-470 and its various features make it the ideal photoresist tool for semiconductor wafer processing applications.
