Thin films have been in used in technology and manufacturing process. Thin films have the general use in many industries and so they are needed. They are commonly used so that a surface that has solid property could be improved in its use. A material that needs absorption characteristic or hardness ability can use thin film to attain it. If a material also needs the permeation, corrosion characteristic, to be reflective, so that it can transmit, the electrical behavior and other characteristics then the thin films could be used.
The nanotechnology also uses the thin film in its industry.
Let us see some applications of it in different categories. One of it is the optic classification that uses the thin films for its coating of the lenses so that it will not be reflective. In mirrors also, they could be used as a coating to reflect or so that there could be decorations to be made. You can see them in CDs and DVDs.
In the field of chemistry, they could also be used as barriers to the diffusion process. They could also be used to protect against the effect of oxidation or corrosion. In the part of mechanic filed they could be used as the tool for reduction of friction. In each uses there are more of it that is not included to be written. Looking into the field of electricity, they are used as capacitors or the resistors.
