A thin film is a layer of materials ranging from fractions of a nanometer to several micrometers in thickness. [1] The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications.
Thin-film optics is the branch of optics that deals with very thin structured layers of different materials. [1] In order to exhibit thin-film optics, the thickness of the layers of material must be similar to the coherence length ; for visible light it is most often observed between 200 and 1000 nm of thickness.
The thickness of the mirror materials must also be optimized to be the quarter wavelength for maximum acoustic reflectivity. The basic principle of the SMR structure was introduced in 1965. [19] Schematic pictures of thin film resonators show only the basic principles of the potential structures.
A thin-film transistor (TFT) is a special type of field-effect transistor (FET) where the transistor is made by thin film deposition. TFTs are grown on a supporting (but non-conducting) substrate , such as glass .
This technique has found applications in many different fields, from semiconductor physics to microelectronics and biology, from basic research to industrial applications. Ellipsometry is a very sensitive measurement technique and provides unequaled capabilities for thin film metrology.
X-ray reflectivity (sometimes known as X-ray specular reflectivity, X-ray reflectometry, or XRR) is a surface-sensitive analytical technique used in chemistry, physics, and materials science to characterize surfaces, thin films and multilayers.

Layer-by-layer (LbL) deposition is a thin film fabrication technique. The films are formed by depositing alternating layers of complementary materials with wash steps in between. This can be accomplished by using various techniques such as immersion, spin, spray, electromagnetism, or fluidics. [1]
