Used EBARA EPO-222D #293749188 for sale

EBARA EPO-222D is an advanced wet grinding, lapping and polishing equipment for precision machining of semiconductor wafers. It is designed to provide an optimal surface finish for large-diameter wafer applications with a wide range of processing capabilities. It is designed with a complex multi-layered drive system, allowing operators to control pressures and speeds specific to each application. The machine utilizes a rotating working surface that is mounted on a stable base. This work surface is placed in a semi-sealed factory environment, making it immune to external dust and preventing cross contamination of the silicon wafers. It is equipped with a highly advanced high-pressure grinding platform and a series of diamond grinding tools that achieve a flat and precise surface finish by removing material layer by layer. The grinding unit is designed to provide precise control over the contact pressure and the relative speed of the diamond grinding tool to the wafer. This allows for tight tolerances even with large area wafers. This unit also uses a liquid cooled grinding environment to optimize the process. It is capable of processing many types of semiconductor materials from silicon and germanium to gallium arsenide and high-temperature superconductors. The machine is equipped with a multi-zone wash section for cleaning of the wafers. This unit is composed of several rotating filters and brushes that help clean both the work surface and the diamond grinding tools before and after each operation. The tool also has a polishing unit that makes use of polishing films and compounds to fine-tune the surface finish. This process can be configured to meet a wide range of surface finish requirements. EPO-222D is also designed with an external cooling asset to prevent thermal damage to the wafer and diamond grinding tool. Its advanced control model, including automatic calibration and real-time monitors, allows operators to continuously monitor the integrity of the process to ensure consistent performance and reduce setup times. The equipment also has real-time CPU monitoring, enabling operators to diagnose and identify any mechanical problems. EBARA EPO-222D is an advanced and versatile solution for precise machining of larger-diameter wafers. With its multi-layered drive system, precise pressure control and a wide range of processing capabilities, it offers a high degree of control and flexibility that can help increase productivity and reduce costs for semiconductor applications.
