Thin Films are Everywhere

Technology devices we rely on every day were primarily possible because of the perfected process of thin film deposition. Our hobbies such as photography or architecture features for construction objects’ sustainability, for example window coatings that preserve heat or cool temperatures inside, our style accessories like sunglasses, and many other things we don’t even notice anymore, depend upon and are created with the use of thin film coatings.

Thin film deposition mainly consists of two steps – the production of thin films, and their deposition (application) onto a surface. Since this process must follow certain strict guidelines, everything must be performed in a highly controlled environment.

Fixed temperatures must be sustained for the production of thin film matter that will be transferred or deposited on another exterior, which also demands a certain environmental state to increase thin film deposition rate for a timely and error free process.

During this transfer of one substance onto another, a complicated network of events takes place to ensure the properties of the future thin film. Under controlled conditions, chemical particles of a deposited material interact with the chemical composition of the surface in order to create the perfect fusion. To reach this perfect fusing of the two, engineers must refer to extremely sensitive tools that control chemical purity, thin film stress and deposition rate.
