Used SEMITOOL SST 421 #9392447 for sale

SEMITOOL SST 421 is a photoresist equipment which is used for advanced patterning processes in the semiconductor industry. It is a fully automated system which provides users with consistent and repeatable results in many of the most challenging resist processes. The unit has two stages: spin-coat and hot-plate. The spin-coat stage utilizes a forced airflow machine for enhanced uniformity of photoresist spin-coating over larger wafer surfaces. This ensures repeatable, high quality photoresist patterns on substrates. The spin-coat stage also has temperature control for coating multiple resist types. The hot-plate stage includes a large processing area for high throughput of substrates with even heating. This even heating improves critical dimension and edge placement accuracy. The tool is also designed with convenience in mind. The motorized substrate stage allows smooth in-tool transportation and handling of substrates. It also has a robotized tool for easy loading and unloading of wafers. Additionally, the asset's touchscreen controller provides user friendly programming and control for simple set-up and operation. SEMITOOL SST-421 has an onboard wafer-level metrology chamber which can monitor layer thickness and other parameters. This ensures high quality patterning results, as well as ease in process control and optimization. The model also offers remote monitoring and control capabilities, allowing users the flexibility to operate and access the tool from any location. Overall, SST 421 is a high performance photoresist equipment that provides quick and reliable results for users, making it a great choice for advanced patterning processes in semiconductor fabrication.
