What is thin film process?
Thin film deposition is the process of creating and depositing thin film coatings onto a substrate material. These coatings can be made of many different materials, from metals to oxides to compounds. There is no one-size-fits-all, perfect thin film deposition system or method.
What is thin film application?
Thin films are generally used to improve the surface properties of solids. Transmission, reflection, absorption, hardness, abrasion resistance, corrosion, permeation and electrical behaviour are only some of the properties of a bulk material surface that can be improved by using a thin film.
Which type of technology is used in thin film?
In the past, majority of thin-film PV cells are made by vacuum-based process. Solution processed thin-film PV cells are highly desirable because it can lower the cost of energy generation. Of most thin-film PV technologies, metal oxides have been acting as key functional layers within the PV cell structures.
What are thin film circuits?
Thin-film technology uses semiconductor and microsystem technology processes to produce circuit boards on ceramic or organic materials. Compared with conventional printed circuit boards and thick-film substrates, however, substrates in thin-film technology usually entail higher costs.
Which techniques are available for processing thin films?
In order to obtain thin films with good quality, there are two common deposition techniques: physical and chemical depositions. It can be summarized as shown in Table 1. Vacuum thermal evaporation. Electron beam evaporation.
What is thick and thin-film technology?
Thin film has a thickness in the order of 0.1 um (micrometer) or smaller, while thick film is thousands times thicker. However, the main difference is the method used to apply the resistive film onto the substrate. Thin film is more accurate, has a better temperature coefficient and is more stable.
How are thick film components produced?
Thick-film circuits are produced primarily by the screen-printing process. Screen printing using silk as the mesh material was an art used by the ancient Greeks and Egyptians to produce signs, designs, and works of art.
Why the thin film laboratory?
The Thin Film Laboratory has contributed highly qualified scientists to R/D institutions, both in India and abroad, and skilled technologists to the domestic industry, some of whom have started their own industry. This has been achieved by sponsoring M.Tech. and Ph.D. research and development projects in the Laboratory.
What are the applications of thin-film devices?
Our laboratory is aiming to develop novel applications of thin-film devices such as organic electronics as well as to explore their fundamental study. More specifically, electronic and/or photonic devices are integrated on the ultra-thin films or rubber sheets to produce next-generation information devices having excellent mechanical flexibility.
Why thin film laboratory of IIT Delhi?
Today, fifty years later, the Thin Film Laboratory of the Physics Department, I.I.T. Delhi, is internationally recognized as a Research School of excellence in the fields of Solid State Physics and Technology of Thin Films.
