WebUtilized in compound semiconductor and silicon device fabrication, Plasma Enhanced Chemical Vapor Deposition (PECVD) systems are designed for the deposition of insulation and passivation films. Samco PECVD systems can deposit high-quality silicon-based thin films (SiO2, Si3N4, SiOxNy, a-Si:H). Samco offers anode PECVD systems for high-quality ... WebSep 9, 2024 · The flow field of precursors in the chamber of ICP-MOCVD was analyzed and the structure of showerhead was optimized by changing the showerhead diameter to obtain uniform velocity field above the substrate. The thickness non-uniformity of GaN films grown at 600 °C was improved from 5.14% to 1.86% after the optimization of showerhead.
