Used NOVELLUS PVD Systems #293669939 for sale

NOVELLUS PVD Systems, also known as physical vapor deposition systems, are essential tools for a variety of industries, ranging from electronics to automotive. PVD Systems are used in a wide variety of processes such as coating, metallization, and electroplating. The process involves the applying of evaporated coatings of metals onto the surface of a workpiece. While various methods are used to introduce the vaporized material onto the surface, the most common is the thermally evaporated process. NOVELLUS PVD Systems are primarily engineered to provide superior film uniformity and process repeatability. This is achieved via their advanced computer controlled system and robotics. The system consists of three primary parts including the vacuum chamber, the vapor source, and the target. The vacuum chamber is where the actual process takes place. Here, the environment is reduced to a high vacuum in order to achieve the desired substrate temperature, while protecting the workpiece from atmospheric contaminants. The vapor source typically resides within the vacuum chamber. Here, the evaporation or sputtering process is initiated by an electric arc, a hot filament, or a glow-discharge. The desired metal is positioned within the vapor source and heated to the point that its atoms become ionized and are eventually ejected into the gas phase. This vaporized material then condenses onto the target substrate. The characteristics of the coating are determined by various operating conditions such as temperature, pressure, and composition of the atomic flux. Finally, the target substrate is the recipient of the vaporized coating. It can be any material that is able to withstand the thermal, electron, or ion bombardment required in the coating process. Typically, the target substrate is very clean and consists of material that is wear-resistant and has good resistance to corrosion. PVD Systems are incredibly versatile and offer the user a remarkable degree of precision and repeatability. Their excellent performance and reliability make them ideal for many different industries. As NOVELLUS PVD Systems become increasingly refined and offering greater control, they will become the preferred method for many different finishings and coatings.
