Used AEROTON Aero 886 #9273222 for sale

AEROTON Aero 886 is a photoresist equipment that provides an environmentally friendly solution for the etching of dies in the production process of semiconductors and other integrated circuits. The system is based on photoresist technology, a method of applying a thin layer of photosensitive material to a substrate which is then irradiated with an ultraviolet light source. In the case of Aero 886, the photoresist technology is conducted in a nitrogen-filled chamber to reduce the exposure to damaging oxidation. The unit uses a set of wafer carriers that are placed inside the chamber. The wafers are transferred into the chamber and an infusion of nitrogen gas is injected to lower the oxidation levels. Once the required vacuum levels are reached, a "blocking layer" is applied to the wafers and exposed to a high-intensity ultra-violet light source. This is the etching stage of the process. During the etching process, the photoresist layer is exposed to the UV light to create a patterned imaged on the wafer's surface. This is achieved using special templates containing design information that is programmed into the machine prior to etching. As the UV light passes over the wafer, the photoresist layer is either exposed or blocked depending on the template pattern. The desired design pattern is then etched into the substrate, producing a fine pattern of miniscule lines and dots known as micromarking. Once the desired pattern has been etched, the tool will then pass a small dose of nitrogen gas across the surface of the wafer to clean off any excess material that could interfere with the photoresist layer. This ensures that once the replacement photoresist layer has been applied, the new pattern will remain in tact. Overall, AEROTON Aero 886 is an effective and efficient solution for etching fine patterns into substrates for various applications. The nitrogen-filled chamber helps eliminate damage due to oxidation and the high-intensity UV light produces accurate micromarking, allowing for precision etching and a high quality end product.
