Plasma Enhanced Chemical Vapor Deposition (PECVD) System

Plasma Enhanced Chemical Vapor Deposition (PECVD) is a versatile thin-film deposition technique that enables low-temperature growth of high-quality dielectric, semiconductor, and polymer films using RF plasma activation. By generating reactive species through plasma, PECVD allows excellent film uniformity, high deposition rates, and superior film properties at substrate temperatures significantly lower than conventional CVD processes.
