Spin Wet Wafer Processing Technology Market

A wafer is a material made of silicon, germanium or other semiconductor material used in the creation of integrated circuits (ICs) which are the building blocks of present day electronics. Spin coating is a process which deposits thin films of material, generally a photoresist on to a single wafer. The photoresist is applied to the center of wafer. The wafer is then rotated at high speed, resulting in centrifugal force which uniformly spreads the photoresist over the entire wafer. The thickness of the film is inversely proportional to the speed of wafer rotation. The process is done by a machine know as spin coater or spin processor or spinner.
