Used SVG 88 #293829338 for sale

SVG 88 is a high precision photoresist equipment designed for the accurate and reproducible nanofabrication of research and development processes. Photoresists are thin layers of photosensitive material applied to a substrate in order to mask certain areas during fabrication. 88 is a vortex spin geometry system which uses a continuous rotation method to uniformly spin the photoresist between the substrate and a spin head. The uniform spinning ensures an even layer of the photoresist over the substrate. SVG 88 utilizes a spray head, making it suitable for larger substrates such as 4x4 cm for substrates up to 8 inch wafers. The spray head is composed of an adjustable nozzle with adjustable RPM, pressure, and steps. This allows the user to tailor the photoresist layer thicknesses to their requirements without compromising accuracy. The photoresist is dipped into a quartz tank and is then applied onto the substrate where it is soft-baked for a few minutes. The photoresist is then exposed to light from a high-power light source that is adjusted to the desired setting. This allows for highly precise exposure of the photoresist relative to the substrate which is not achievable with other photoresist systems. The photoresist is then baked on a hot plate to fix the image and improve the structural robustness of the photoresist. 88 also features a digital control unit for temperature and vacuum control, allowing for precise and consistent dry-etching of the photoresist. This photoresist machine is designed to provide maximum accuracy with minimum waste, helping reduce overall costs and improving productivity. It is an ideal choice for nanofabrication processes such as thin film deposition and lithography which require a high degree of precision and reproducibility.
