Used SEMITOOL SST #293654402 for sale

SEMITOOL SST is a photoresist equipment used in semiconductor fabrication. It is a process that combines a chemical coating known as a resist, along with vertical spin processes, to achieve a lithography effect for the creation of desired device-level features. The vertical spin is key to this system, as it creates a more uniform coating on the substrate, preventing residue build-up and improving hole-and-line placement accuracy. SST is used for modern lithography processes, such as thin-film transistor (TFT), complementary metal-oxide-silicon (CMOS) and semiconductor memory cells. It features variable spin speeds, adjustable resist thickness, and precise resist spray patterns which enable devices of various shapes and sizes to be created with a minimum of non-uniformity. Its repeatability and accuracy ensure device specifications are met, while its versatility allows different processes to be performed with just one unit. SEMITOOL SST is also designed for compatibility with low-viscosity resists, allowing for higher spinning speeds and higher resolution, resulting in more accurate and reliable device-level features. The machine is outfitted with a reliable solvent-resistant handheld sprayer and high-pressure pumps for precise control over the resist thickness and flow rate. SST is designed to minimize overspray and contamination, while providing a low-maintenance tool with proven reliability over extended use. Its powerful versatility, accuracy and reliability make SEMITOOL SST invaluable in the production of compact transistors, flip-chip assemblies, 3D integrated circuits and other complex device-level fabrication projects.
