Used SEMITOOL SST-642 #293587516 for sale

SEMITOOL SST-642 Photoresist Equipment is a state of the art system designed for processing photoresist. It is used in the production of circuit boards and other precision applications where extremely small and detailed features are necessary. The unit utilizes a vacuum diffusion pump to create low levels of pressure and temperature while maintaining the necessary level of cleanliness. The vacuum diffusion pump is capable of maintaining consistent temperatures and pressure gradients in the processing chamber during different stages of the photoresist process, thereby providing a consistent output even with changes in ambient temperature or humidity. SST-642 also includes a highly precise, high-resolution stepper motor that provides direct control over the spin speed of the substrate, as well as direct control of the substrate heating and cooling while the machine is in operation. The stepper motor allows for extreme precision and accuracy when processing the photoresist. The stepper motor also allows the substrate to move both up and down in the chamber for even processing throughout the entire chamber. SEMITOOL SST-642 also comes with a pump out tool for removing contaminated liquid from the processing chamber. This asset utilizes a highly effective filtration model to remove particulates from the liquid being processed and prevents contamination from entering and damaging the substrate. This also aids in maintaining a consistent level of cleanliness in the chamber regardless of the substrate being processed or the complexity of the process being completed. SST-642 also includes a built-in imaging and analysis equipment so that during process monitoring the user has the ability to analyze the photoresist layers and their effects on the work pieces at any given time. This advanced imaging and analysis system is able to detect minute changes that may occur and alert the user of any possible irregularities in the process. SEMITOOL SST-642 features a process chamber lined with ceramic material that minimizes energy loss throughout the entire process. The entire unit, when properly maintained, has a proven track record of low downtime and high efficiency in processing photoresist for the most demanding applications. With its advanced and automated features, SST-642 is the perfect solution for precision applications requiring high levels of accuracy and consistency in photoresist processing.
