Used EBARA Frex 300 #293743768 for sale

EBARA Frex 300 is an advanced, fully automated wafer grinding, lapping, and polishing equipment used in the fabrication of semiconductor wafers. The sophisticated system includes two separate process modules, each of which may be configured to operate either independently or in sequence. The unit provides improved wafer surface-prep capabilities for any type of wafer substrate, such as silicon, single-crystal silicon, and insulating films. The integrated dual-module approach allows the user to select the best processing conditions suited to a given wafer, from precision grinding, to high-accuracy lapping, to ultra-fine polishing. It is designed to save time and increase throughput by efficiently managing a wide range of wafer pre-processing techniques. The grinding module consists of a high-torque, adjustable-speed motor coupled to a grinding wheel for precision-shaping of wafers. The grinding wheel can be programmed with the specific grinding parameters to achieve the desired surface finish, making it an ideal choice for complex shapes. The grinding module utilizes an adjustable-force mechanism with precision-contoured feedback mechanisms to maintain an exact surface finish with very tight parameters. The lapping module is designed to remove surface defects and provide a smooth, uniform surface finish. The machine employs a sophisticated pressure-control tool to adjust the force to the wafer surface to ensure uniform and consistent results. An integral feedback asset continually monitors the grinding and lapping process for consistent results. A flatness measure is also used to ensure a flat, defect-free surface. The polishing module is essential for achieving the best possible surface finish on wafers. This module utilizes an adjustable-speed motor to drive a polishing pad while an adjustable-force mechanism maintains a uniform pressure on the surface of the wafer. The model is equipped with an optical polishing monitor and a high-resolution imaging equipment to provide unparalleled control over the polishing process. EBARA FREX-300 is a highly sophisticated, automated wafer grinding, lapping, and polishing system used in semiconductor fabrication. The dual-module approach and advanced feedback unit provide the user with unprecedented levels of control over the wafer surface-preparation process. The machine is capable of producing surfaces with tight tolerances and minimized defects in short cycle times.
