Ion Beam Deposition (IBD) is a thin-film deposition technique in which source material is ionized, accelerated by an electric field, and deposited onto a substrate. Gas Cluster Ion Beam (GCIB) deposition, a specialized form of this technique, utilizes ionized clusters of atoms to produce high-quality films with excellent crystalline properties, often with less damage to the substrate compared to monomer ion beams.
Clusters are aggregates containing tens to thousands of atoms or molecules. When formed from a gas source, they are known as gas clusters. These are generated through adiabatic expansion, where high-pressure gas expands through a nozzle into a high-vacuum chamber, cooling and condensing into clusters. These clusters are subsequently ionized, typically via electron impact.
In this process, high-energy electrons bombard the clusters to strip away electrons, giving them a net positive charge. An electric field then accelerates these ionized clusters toward the substrate. This technique is widely used for precision thin-film deposition and surface modification.
High-voltage power supplies are a core component in ion beam deposition systems. They are critical for functions such as ion beam acceleration, extraction, suppression, deflection, grid biasing, and neutralization. Matsusada Precision offers a wide range of power supplies optimized to meet the demanding stability and reliability requirements of these applications.
