Used SEMITOOL SST-F-421-280-F #9276688 for sale

SEMITOOL SST-F-421-280-F is a photoresist equipment designed to accurately control the patterning of integrated circuitry on a silicon wafer. This system features a four-axis gantry and three-axis stage to provide the exact alignment necessary for accurately patterning circuits. The gantry holds a spin-coater and wafer dispense robot, while the stage is capable of accurately controlling the wafer's position relative to the spin coater and dispense robot. Photoresist is a light-sensitive chemical compound that is applied to the printed silicon wafer, and when exposed to light, produces a patterned electrical insulation layer which isolates circuits from one another. The photoresist unit uses a combination of high-powered lasers, optical systems, and advanced control algorithms to provide accurate control of the photoresist's exposure. SEMITOOL SSTF 421280F machine also houses a spin processor, which allows the wafer to be spun at high speeds creating thin, even layers of photoresist over the printed surface. Additionally, the tool is compatible with both wet and dry photoresist processes, allowing it to be used with various photoresist types, such as positive-tone, negative-tone, and natural angle. To aid with the photoresist process, the asset also includes several process monitoring features, such as an automatic temperature control model, a precision stitcher for uniform exposure, and a surface contamination monitor. Furthermore, several quality assurance and defect detection features are also included, such as in-situ defect inspection and an integrated process control equipment. Once the patterning process is complete, the system can then be used in conjunction with photolithography and etching processes to create the desired circuit patterns. The combination of features provided by SST-F421-280-F unit make it one of the most effective solutions for accurately patterning sophisticated integrated circuits on silicon wafers.
