Used IPEC / WESTECH / SPEEDFAM Avanti 472 #9382965 for sale

IPEC / WESTECH / SPEEDFAM Avanti 472 is a wafer grinding, lapping, and polishing equipment designed for advanced semiconductor device fabrication. This system is capable of processing up to four 12 inch wafers at a time, while producing extremely flat surfaces with superior cross-sectional shape. IPEC Avanti 472 features heavy duty construction and components that are built from the highest quality materials for reliable performance in even the most demanding production environments. WESTECH Avanti 472 is designed to provide perfect parallelism between the faced surface gold cap growth phase and the wafer disc surface, enabling faster and more accurate polishing. The unit utilizes a slurry flow machine that maintains a constant flow and polishing behavior while creating a longer lasting polish. The use of adjustable settings and a direct drive motor ensures precise positioning for a perfect finish. Avanti 472's lapping process is automated and utilizes a four-stage grinding tool which ensures repeatability and helps reduce overall chip-to-chip variation. The asset features a multi-level feedback control mechanism which allows for fine-tuning of process parameters for optimal performance. A top-of-the-line optical model enables particle size analysis, so that the equipment can be tuned-in to meet specific size, shape, surface finish, and uniformity requirements. The system also has a unique and innovative polishing methodology which helps in removing any debris from the wafer surface while also maintaining desired grinding and lapping parameters. This unit features a wafer carrier and a double disc polishing head which provides even pressure distribution across the surface of the wafer. The double disc polishing head also serves to provide the wafer with a consistent finishing touch. SPEEDFAM Avanti 472 is equipped with a brushless servo-controlled motor which provides extremely efficient, reliable performance while minimizing noise and vibration levels. The machine also offers a variety of safety features such as air and sound damping, vibration proofing, automatic shutoff, and automatic thermal protection. This ensures safe and accurate operation. IPEC / WESTECH / SPEEDFAM Avanti 472 is a top-of-the-line wafer grinding, lapping, and polishing tool designed for advanced semiconductor device fabrication. It is capable of precision grinding and polishing operations while providing exceptional repeatability and consistent results.
