Industries That Need Spin Coatings

Silicon Wafers Held in Hands

Spin coating involves applying a thin coat of liquid over an object while the object is turning. The liquid then cools, and some parts of the coating may evaporate, to achieve various effects. The main idea is that the spinning action spreads out the coating to a perfectly even thickness over the desired material. Spinning also dries the liquid in a controlled environment. Centripetal force allows this process to happen. Coating Systems explains industries that utilize spin coating as a way to protect or enhance their vital products.


Semiconductors, most notably computer chips and microchips, benefit from spin coating techniques. Film over semiconductor wafers not only protects the sensitive circuits inside the chips, but they can also enhance electrical currents over the small circuits to make them more efficient. Semiconductors often need coatings around 10 nanometers thick for optimal results. The coating process ensures an even distribution of the liquid down to those microscopic thicknesses.

Consumer Electronics

Manufacturers of consumer electronics use spin coating on television screens. Various coats of clear liquid can increase visual acuity of screens while also offering protection from the immediate environment, resulting in a higher-quality product. CDs, DVDs, and Blu-ray discs utilize this coating technique to produce layer upon layer of thin coatings for better readability and protection from nicks, dings, and scratches.

Nanotechnology benefits from spin coatings in major ways. Manufacturers can create layers of nanotubes and nanoparticles in precise fashion. For instance, one layer of carbon nanotubes goes down first. Once that layer dries, a second layer is applied that may go in a perpendicular direction. Sometimes, this technique is the only way to achieve certain effects and layers based on drying times of each layer and the microscopic levels at which nanotechnology operates. Spin rates and RPMs often determine drying times for each layer. When nanotubes align properly at the microscopic level, these technologies work their best.
