Spin Coating: Complete Guide to Theory and Techniques
Spin Coating Thickness Equation. In general, the thickness of a spin coated film is proportional to the inverse of the square root of spin speed as in the below equation where ω is angular velocity/spin speed and h f is final film thickness. Equation 1: Spin coating thickness equation
A Modified Equation for Thickness of the Film Fabricated by Spin Coating
2019年9月18日 · According to the equation for Newtonian fluids, the film thickness after spin coating is determined by five parameters: angular velocity, spin coating time, viscosity, density of the coating material, and initial thickness of the material before spin coating.
Basic Models of Spin Coating
Spin coating is a widespread practice in modern science and engineering, where it is used to deposit uniform coatings of organic materials and/or to uniformly distribute particulate matter on a flat surface.
Spin coating is a method to prepare thin and utra thin films of a soluble material on a solid substrate. The material is spread on a disk-like substrate and under rotation it is partially removed by centrifucgal forces to form a homogeneous film.
Spin coating is currently the predominant technique employed to produce uniform thin films of photosensitive organic materials with thickness of the order of micrometers and nanometers.
Spin coating is a procedure used to apply uniform thin films to flat substrates. A typical process involves depositing a small puddle of a fluid resin onto the center of a substrate and then spinning the substrate at high speed (typically around 3000 rpm) (Mitzi et al. 2004).

The Equation for Spin Coating Thickness: The thickness of a film that has been spin-coated is proportional to the inverse of the squared spin speed as follows: Here: hf: final film thickness. ω: angular velocity/spin speed. Indicates: the thickness of a film will be reduced by one-fourth when it is spun at four times the normal speed. Models:
