Used SPEEDFAM 12B-6L #9007407 for sale

SPEEDFAM 12B-6L is a wafer grinding, lapping and polishing equipment used in semiconductor fabrication. With 6 grinding wheels, the system is capable of accurately and quickly grinding semiconductor wafers to provide the desired surface finish and dimensional accuracy. The unit is designed for superior quality and reliable performance, allowing for both low and high volume production. 12B-6L features a 30-inch, steel-enclosed chamber with transmission forced air ventilation which permits effective temperature control that is essential for attaining uniform polishing of all wafers in the machine. The tool also eliminates the possibility of wafer breakage due to excessive grinding pressure and temperature. The 6 grinding wheels are individually adjustable on the table and can be programmed for automatic repetitive grinding sequences. SPEEDFAM 12B-6L also features a Work Flow Monitor (WFM), a process control asset that helps to maintain uniformity and repeatability every cycle, ensuring that wafers retain their desired shape and surface finish. This model uses programmable memory cards to ensure the delivery of consistent results for each wafer size and thickness. To maintain the highest quality standards during production, 12B-6L uses a "Safety Interlock" which prevents operational accidents due to human error. It has a twelfth generation lapping plate positioned over the grinding wheels that performs edge and surface burr removal. In addition, the motorized work head is adjustable to a variety of angles OSA (optical spherical aberration), producing wafers with high accuracy and clear images. The equipment is equipped with a computer monitor and printer which provides a digital record of all production runs. This provides a data log of the finished wafer count, abrasive cycle number and time, polishing parameters and wafer surface conditions. This log is then printed out, allowing for further analysis of the data, review of the process and continual optimization. SPEEDFAM 12B-6L is a reliable system that eliminates time consuming manual operations, thereby improving production. With its high accuracy and repeatability, it is an important tool for semiconductor fabrication.
