System dedicated to the deposition of thin and ultra-thin films deposited by electron beam evaporation.
The electron beam evaporation is a physical vapor deposition in which high-energy electrons impinge on the material to be deposited, typically in the form of rods or pellets, inducing its sublimation and the following deposition on a substrate. Inside the vacuum chamber, the target material is placed in a pocket crucible where it is easily irradiated by the electron beam. The system employs a multi-crucible system that allows the deposition of multilayers. To improve the homogeneity of deposition, the substrates are mounted on a rotating holder whose speed can be controlled by the operator.
This technique is indicated for deposition of thin films of metals, semi-metals, oxides and fluorides with thickness ranging from few monolayers to few µm.
