This discharge, carried out within a rarefied atmosphere, under vacuum<\/strong>, allows the making of a plasma composed of charged particles (electrons, ions, photons) and neutrals (atoms). The electric field generated by the difference in potential induces a movement of positively charged particles that are attracted by the cathode (target) and collide with it. This bombardment causes the sputtering of atoms or aggregates of atoms<\/strong> from the target which will condense on the substrate. On a macroscopic scale, this physical phenomenon could be compared to a \u201cbilliard breakage\u201d. In order to have an effective sputtering rate, the plasma gas<\/strong> used for this technology is the argon gas. Its atomic mass, its neutrality (complete valence shell), as well as its cost are ideal.<\/p>\n The main steps are:[\/vc_column_text][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n Collision of incident ions on the target resulting in a transfer of kinetic energy and motion amount.<\/p>\n [\/vc_column_text][vc_single_image image=”2745″ alignment=”center” onclick=”zoom”][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n Emission of atoms<\/strong> or aggregates with a given kinetic energy that settle down on the substrate and become a thin film of target material.<\/p>\n [\/vc_column_text][vc_single_image image=”2318″ alignment=”center” onclick=”zoom”][\/vc_column_inner][\/vc_row_inner][vc_column_text]This technology, commonly used in the industry of thin films<\/strong> for the semiconductor industry, sees its number of applications increase.\u00a0 Being a clean technology, it is a realistic and practical alternative to wet treatments.<\/p>\n The great majority of this type of PVD equipment<\/strong> uses magnetron cathode sputtering technology<\/strong>.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]Vacuum Evaporation<\/span><\/strong><\/p>\n Unlike magnetron cathode sputtering<\/strong> or diode cathode sputtering<\/strong> which is based on a mechanical principle of atomic bombardment or more exactly ionic bombardment<\/strong>, vacuum evaporation<\/strong> is based on a thermal principle. Thus, the heating allows the material to reach its melting point first and its evaporating point in a second time.<\/p>\n Vacuum evaporation<\/strong> is based on two basic processes: evaporation from a heated source and condensation in the solid state of the evaporated material on the substrate.[\/vc_column_text][vc_row_inner gap=”15″][vc_column_inner width=”2\/3″][vc_column_text]The heating of the material can be generated by several techniques:<\/p>\n These technologies enable to control in a very precise manner the deposition thickness.

In fact, if we try for example to make a metal deposition at atmospheric pressure<\/strong>, this would lead to the growth of a metal oxynitride film deposition<\/strong> of this metal given the presence of dioxygen and nitrous oxyde<\/strong> in the air.[\/vc_column_text][\/vc_column_inner][vc_column_inner el_class=”blocmachine” width=”1\/2″ css=”.vc_custom_1574603414272{background-color: #eeeeee !important;border-radius: 10px !important;}”][vc_column_text]Can all types of material can be deposited?<\/strong><\/p>\n Metal materials, ceramics, oxides, nitrides, etc., can be synthesized with these technologies.
