The networks (matchboxes) Physical Vapor Deposition (PVD) by Sputtering Physical Vapor Deposition (PVD) is a process by which a thin film of material is deposited on a substrate according to the following sequence of steps: 1) the material to be deposited is converted into vapor by physical means; 2) the vapor is transported across a region of low pressure from its source to the substrate; and 3) the vapor undergoes can thus conclude that DC sputtering mode, high sputtering power density, low substrate bias voltage and low substrate temperature are more suitable for the fabrication of pure Cu films; on the contrary, RF sputtering mode, low sputtering power density, high substrate bias voltage and high substrate temperature DC, pulsed DC, AC and RF power supplies may be used, depending upon target material, if reactive sputtering is desired and other factors. Quorum offer low-cost, rotary-pumped sputter coaters for depositing non-oxidising metals - such as gold (Au) and platinum (Pt) - and turbomolecular-pumped coaters, suitable for both oxidising and non-oxidising metals, such as chromium (Cr). Reactive sputtering is a process that allows compounds to be deposited by introducing a reactive gas (typically oxygen or nitrogen) into the plasma which is typically formed by an inert gas such as argon (most common), xenon, or krypton. 20320Types. • A plasma is created by ionizing a sputtering gas (generally a chemically inert, heavy gas like Argon). Rf sputtering can be used with a magnetic field in balanced and unbalanced configurations to obtain a result similar to dc-like diode discharge. The energetic atoms in this gas plasma collide with the target material and knock off source atoms which then travel to the substrate and condense into a thin film. 5-30 MHz). The surface of the target is eroded by high-energy ions within the plasma, and the liberated atoms travel through the vacuum environment The use of a DC or RF excitation field depends mainly on the target’s electrical properties; DC power can be used for metallic targets, while RF sputtering is used for insulating targets.
