What is “sputtering”?<\/em><\/h2>\n\n\n\n

Sputtering<\/strong> is a Physical Vapor Deposition (PVD) technique<\/em><\/a> used to create thin films<\/strong> on a substrate through the ion bombardment<\/strong> of a solid material, known as the target. The process is based on the controlled ejection of atoms from the target which, once released, deposit onto the surface to be coated, forming a compact and adherent layer.<\/p>\n\n\n\n

Physical Principle: Plasma and Ion Bombardment<\/em><\/h2>\n\n\n\n

Sputtering takes place inside a vacuum chamber into which an inert gas, usually argon, is introduced. By applying a negative electrical potential to the targets<\/strong>, a plasma is generated, an ionized gas composed of electrons and positive ions.<\/p>\n\n\n\n

The positive argon ions, accelerated by the electric field, strike the target<\/strong> with sufficient energy to eject atoms from its surface. This phenomenon, called ion bombardment, is purely physical (not chemical). The ejected atoms travel through the chamber and condense on the substrate, forming a thin film with high density and good adhesion.<\/p>\n\n\n\n
