Used AMAT / APPLIED MATERIALS Mesa #293614950 for sale

AMAT / APPLIED MATERIALS Mesa is an automated, closed loop, robotic equipment that is used in the fabrication, grinding, lapping and polishing of wafers and other semiconductor material. It features the latest in in-situ process control technology, allowing for the optimization of step-and-repeat process geometries, ensuring the highest level of precision and repeatability. The system is designed to process wafers with various substrate types, shapes and sizes. The unit is equipped with an advanced robotic control machine as well as multiple motion axes and a robotic arm for wafer handling. The control tool can be used to program various surface preparation operations, such as lapping, grinding, buffing and polishing. The robotic arm positions the wafer on the lapping block, allowing for the precise and repeatable positioning of each individual wafer. The asset also includes a solar cell inspection station to verify that each processed wafer is free of defects before wafer engagement. A substrate transport and loading model is also provided to facilitate the maximum utilization of the equipment's capabilities. The robotic controller and substrate transport system can be integrated with other automated systems such as optical inspection, electrical resistance testing and thermal imaging systems. Also included is a wafer lapping, buffing and polishing station, in which lapping stones, abrasives and working products can be loaded and unloaded via the unit's multi-axis robotic arm. This station is capable of producing a wide variety of polished surfaces, and can be customized to fit the needs of specific processes. The machine can be interfaced with an environmental chamber, allowing for the processing and inspection of wafers in a controlled, contaminant-free atmosphere. The tool's contamination control mechanisms include the use of the environmental chamber, temperature and humidity monitoring and control, and particle counting. In addition, the asset's vacuum model can evacuate the chamber, ensuring a low contaminate environment. AMAT Mesa equipment is a reliable and highly advanced system for the fabrication, grinding, lapping and polishing of wafers and other semiconductor materials. Its sophisticated robotic control unit allows for the repeatable, tailored processing of each individual wafer, while its comprehensive contamination control mechanisms ensure the production of only the highest quality wafers.
