Used SEMITOOL SST 421 #9292694 for sale

SEMITOOL SST 421 photoresist system is a versatile and reliable tool used for a variety of semi-conductor manufacturing tasks. It is capable of coating substrates, polymerizing photoresists, striping photoresists, and etching substrates. The machine is composed of a De-ionized Water Control, Resist Coating and Resist Strip Modules, Photoresist and Ion Milling Modules, and a Thermal Oxidation Oven. The De-ionized Water Control Module features two reservoirs and pumps that are designed to deliver exact quantities of de-ionized water. The water is used to rinse substrates as well as in other operations, making it an integral part of the system. The Resist Coating and Resist Strip Modules are designed to deliver precise coating solutions, including photoresists, onto substrates. The Photoresist and Ion Milling Modules are designed to polymerize photoresists and etch substrates respectively. They can both be configured for various processes and geometries. The Thermal Oxidation Oven allows for several oxidation processes to be carried out on substrates. It also boasts adjustable temperature settings and a rapid heating element, enabling users to complete multiple oxidation steps in a single cycle. Overall, SEMITOOL SST-421 offers flexibility and precision for a variety of semi-conductor manufacturing tasks. Substrates can be rinsed using de-ionized water and then coated with photoresists and spun to a predetermined thickness. The photoresist can then be polymerized in the Photoresist and Ion Milling modules and etched into a desired shape. Finally, the substrates can be oxidation-processed in the oven. This allows users to complete complicated semi-conductor manufacturing processes in a single cycle. Moreover, its flexibility means it can be adapted to a variety of processes and geometries, making it a reliable and cost-effective tool for semi-conductor production.
