Spin coating is a technique used to spread uniform thin films on flat substrates by centrifugal force. The apparatus used for spin coating is called a spin coater, or a spinner.
What is spin coater machine?
A machine used for spin coating is called a spin coater, or simply spinner. Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved. The applied solvent is usually volatile, and simultaneously evaporates.
Why spin coating method is widely used for the photolithography?
Spin-coating is the most widely deployed method for dispensing photoresists and other materials uniformly onto substrates. Spin-coating is used to produce thin films of the desired material with high levels of process control and repeatability. ... The substrate is then spun at high speeds in the range of 500 – 4000 rpm.
