Laurell Technologies WS-400 spin coater used to apply photoresist to the surface of a silicon wafer. Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material in liquid form is applied on the center of the substrate, which is either spinning at low speed or not spinning at all.
For example, a whole car has been coated with spray assembly, optically transparent films have been prepared with spin assembly, etc. [1] Characterization of LbL film deposition is typically done by optical techniques such as dual polarisation interferometry or ellipsometry or mechanical techniques such as quartz crystal microbalance.
Modern automobile paint is applied in several layers, with a total thickness of around 100 μm (0.1mm). Paint application requires preparation and primer steps to ensure proper application. A basecoat is applied after the primer paint is applied. Following this, a clearcoat of paint may be applied that forms a glossy and transparent coating.
There are four basic parameters that are involved in spin coating: solution viscosity, solid content (density), angular speed, and spin time. [13] A range of thicknesses can be achieved by spin coating. Most commonly the thicknesses range from 1-200 μm. The main properties that affect the thickness of the film are viscosity and spin speed.
Coatings help to protect the machines form rust and extend their life cycle. In this industry, product branding plays a big role for many companies trying to differentiate themselves, so high quality finish is a strong factor for many manufacturers.
