A thin film is a layer of material ranging from fractions of a nanometer to several micrometers in thickness. Thin films can be composed of various materials, including metals, semiconductors, insulators, and polymers. They are often deposited onto substrates (like glass, silicon, or metals) using various techniques, such as physical vapor deposition (PVD), chemical vapor deposition (CVD), sputtering, and spin coating.
