Used IPEC / WESTECH / SPEEDFAM 472 #9230899 for sale

IPEC / WESTECH / SPEEDFAM 472 is a wafer grinding, lapping and polishing equipment for the production of semiconductor wafers. It is specifically designed for the reliable and precise production of high-quality wafers in a continuous flow process. IPEC 472 system features a fully automated set-up and operator control, a proprietary CNC (Computer Numerical Control) motion control unit for precise movement and high accuracy, and a patented high-resolution metrology machine for automated self-monitoring and self-tuning of the grinding and polishing operation. The tool has been designed to be as efficient as possible, optimizing time and cost. The asset consists of a main production tower, where wafers are loaded, ground, lapped and polished. The tower is controlled by a 6-axis, high-torque CNC machine which can adjust the speed, pressure, tilt, and depth of grinding, as well as variable lapping and polishing parameters. The grinding and polishing stages can be easily modified for different product requirements. There is an independent side-shifting device for easy orientation of the wafer to be processed on each grinding head, and a tilting and rotating belt drive to ensure proper contact between the grinding and polishing surfaces. In addition, the model has a fully automated diamond lapping and polishing station, with fully programmable and adjustable spinning speeds. The equipment also includes a proprietary high-resolution metrology system to measure the wafers throughout the grinding and polishing process. This measure can be used to provide real-time feedback on the quality of the grinding and polishing job, allowing for automatic self-tuning. This ensures the high quality standards needed to produce high-performance wafers. In addition, WESTECH 472 unit also features a powerful off-board chiller and pumping machine to reduce noise and vibration, making it suitable for use in cleanroom environments. 472 is ideal for semiconductor wafer production, providing maximum levels of accuracy, reliability and cost-efficiency. With its easy to use programmable automation, combined with its advanced metrology and measurement capabilities, it provides the perfect solution for producing high-quality, high-performance wafers.
