WebAug 26, 2024 · Spin coating is widely used to form a uniform film on a solid substrate. Airflow disturbance has been considered as one of the most influential factors of film … Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material is applied on the center of the substrate, which is either spinning at low speed or not spinning at all. The substrate is then rotated at speeds up to 10,000 rpm to spread the coating material by centrifugal force. A machine used for spin coating is called a spin c… WebSep 30, 2024 · The thickness uniformity of the spin-coated sacrificial layer plays a significant role in switch fabrication. The spin-coater leveling and cleaning of the substrate are done to achieve a uniform thickness profile of HiPR 6517.
