Used SPEEDFAM DSP 18B-5P #9170546 for sale

SPEEDFAM DSP 18B-5P wafer grinding, lapping and polishing equipment is a highly advanced and automated, single-wafer, surface conditioning system used for silicon wafer and other materials with demanding surface preparation requirements. This unit is ideal for large wafers, ranging from 50mm to 200mm in diameter, and is capable of achieving atomic level, low-edge-roughness surface finishing capabilities. DSP 18B-5P is equipped with a closed-loop high-precision positioning machine, which features a quartz encoder mounted on the spindle for precise microstep control. This combination of open-loop and closed-loop control algorithms allows for repeatable processes and ensures highly precise and accurate polishing results. The tool offers a choice of both single-sided grinding and polishing (with a single station) or double-sided simultaneous grinding and polishing (with four stations) with a unique patented processing technique. This full-contact grinding and polishing mode provides uniform, constant pressure to the wafer surface, resulting in highly uniform surface finishes and superior quality. SPEEDFAM DSP 18B-5P processes a wide variety of substrates, including single crystal substrates, glass, and ceramics. A unique Delta Cu Asset is incorporated to precisely control the process pressure, resulting in uniform, repeatable surfaces. Utilizing an advanced vacuum polishing model, DSP 18B-5P minimizes waste and contamination. The equipment incorporates variable speed technology to fine-tune the process parameters and maintain the exact contact pressure throughout the process. Each of the processing steps is automatically monitored in real-time, and the results are logged and stored for future reference. The system's robust design also includes a touch screen interface, upgraded safety features, and a range of accessories for further automation. With its robust, tactile design and advanced features, SPEEDFAM DSP 18B-5P is the ideal solution for any application that requires consistent, superior polishing results.
