Spin coat thickness

WebSpin coating is a very common technique to deposit uniform thin films onto flat substrates by centrifugal force. It mainly involves four stages: fluid dispense, spin up, spin off, and evaporation. The substrate is attached to a turntable via high vacuum and its high spinning speed results in thinning of the deposited layer. Webface of the substrate. The spin coating process has been studied extensively in the past and much is known about factors that control coating deposition and the final thickness ofthe deposit that results [1-10]. The present review of spin …
