・External Accessories: A2K Series / MFU
These products are equipped with features to address challenges in the sputtering process and can be utilized across a wide range of fields and applications, from research and development to production lines.
Pulse and DC power supply systems are primarily used as power sources in PVD (sputtering) processes. Sputtering enables the formation of various films, including metal films, alloy films, oxide films, nitride films, and transparent conductive films. These films are created by adjusting sputtering conditions such as target material, gas composition, pressure, and power. Due to this versatility, sputtering technology is utilized across a wide range of applications. In general, DC power supplies are used for sputtering metal films, while DC pulse power supplies and LF power supplies are suitable for forming oxide or nitride films through reactive sputtering. Additionally, the optimal power supply can be selected according to the specific requirements of the process. ULVAC’s pulse and DC power supply systems leverage extensive expertise gained from various applications to support high-quality film formation processes. We encourage you to take full advantage of these systems.
