Spray coating involves spray application of the solution to the wafer through a nozzle. The path traveled by the nozzle over the wafer is optimized to ensure that the coating is applied evenly to the substrate. The solutions used in spray coating usually feature a very low viscosity, which guarantees that fine droplets form.
Spray coating ensures a uniform layer even with high topography substrates, making it the preferred technique for structures of this kind. Even square substrates can be easily coated using the spray technique.
