Used SVG 90 #293747980 for sale

SVG 90 is a photoresist equipment used in the fabrication of semiconductor devices such as transistors. It is a negative working, deep-UV chemically amplified photoresist which allows the delivery of sub-micron geometries on a wide range of substrates, including silicon, Nitride, Glass and silicon-on-insulator (SOI) substrates. 90 system is primarily composed of the two components - the photoresist and a developer. The photoresist is a light-sensitive, liquid polymer which hardens when exposed to UV light, forming a protective mask on the wafer. The developer is a solution used to dissolve and remove the photoresist after it has been exposed and hardened by UV light. At the facility level, SVG 90 unit is composed of several subsystems. This includes, but is not limited to, a stepper (used to project imaging onto the photoresist layer), a bake machine (used to evaporate the photoresist), a processing chamber, and a developer tool (used to clean up the photoresist). 90 asset requires a high level of precision and accuracy. Its capability of creating sub-micron geometries, while also providing a high degree of depth control, makes it ideal for semiconductor device production. To ensure optimal results, these production protocols must be strictly followed. For instance, the stepper model requires precision placement and alignment of the photomask and wafer prior to exposure in order to achieve desired results. It is also important to adhere to recommended bake temperatures, which vary depending on the photoresist used. Finally, the developer equipment must be carefully monitored to avoid over or under-exposure of the photoresist. Overall, SVG 90 is a reliable, easy-to-use system that is used to produce a variety of semiconductor devices. Its precision, scalability and versatility makes it a popular choice for device manufacturers.
