The speed of PECVD (Plasma-Enhanced Chemical Vapor Deposition) is notably high, with deposition rates ranging from 1 to 10 nm/s or more, significantly faster than traditional vacuum-based techniques like PVD (Physical Vapor Deposition). For instance, the deposition rate for silicon nitride (Si3N4) using PECVD at 400°C is 130Å/sec, compared to 48Å/min for LPCVD (Low-Pressure Chemical Vapor Deposition) at 800°C, which is approximately 160 times slower.
PECVD achieves these high deposition rates by utilizing plasma to provide the necessary energy for chemical reactions to occur, rather than relying solely on heating the substrate. This plasma activation of precursor gases in the vacuum chamber promotes the formation of thin films at lower temperatures, typically ranging from room temperature to about 350°C. The use of plasma in PECVD not only accelerates the deposition process but also allows for the coating of substrates at lower temperatures, which is beneficial for materials that cannot withstand high thermal stresses.
The high deposition rates of PECVD make it a preferred choice for applications requiring rapid and efficient thin film deposition, especially when dealing with materials sensitive to high temperatures or when rapid production cycles are necessary. This efficiency in deposition is a key factor in the reliability and cost-effectiveness of PECVD as a fabrication technology.
