Plasma-enhanced chemical vapor deposition (PECVD) is a chemical vapor deposition process used to deposit thin films from a gas state to a solid state on a substrate. Chemical reactions are involved in the process, which occur after creation of a plasma of the reacting gases.

Plasma-Enhanced Chemical Vapor Deposition: PECVD PECVD is a fabrication method for depositing thin films on a wafer. PECVD is used to deposit SiO2, Si3N4 (SixNy), SixOyNz and amorphous Si films. In this method of CVD, plasma is added in the deposition chamber with reactive gases to create the desired solid surface on the substrate.

Our PECVD Nitride is a single sided film that has been optimized for wafers requiring minimal thermal processing. Because PECVD Nitride is deposited at low temperatures, it offers greater flexibility and can be deposited over any of our other thin films.

High density plasma chemical vapor deposition is a version of PECVD that uses a higher density plasma, which allows the wafers to react with an even lower temperature (between 80°C-150°C) within the deposition chamber. This also creates a film with great trench fill capabilities.

PECVD nitride on silicon wafers is the latest technology to produce silicon nitride on silicon. Unlike the traditional LPCVD process, it is also highly reproducible, uniform, and high-quality. The PECVD process is ideal for passivation layers because it allows for faster growth rates.

enhanced chemical vapor deposition (PECVD) is a viable alternative. The Plasmalab 80 Plus (referred to as Oxford2 in the lab) PECVD machine has a common PECVD set up 1 , with a parallel plate capacitor and low and high frequency generators.

Aug 29, 2024 · ACM Research’s Ultra Pmax™ plasma-enhanced CVD (PECVD) technology, based on TEOS and O 2 chemistries, enables > 3:1 aspect ratio TSV barrier layer for copper gap fill. Its ability to accommodate low-temperature processing ensures better process control and evenness of layer thickness during the deposition process.

Transferring standard PIC (photonic integrated circuit) processes from smaller wafer sizes to 300 mm wafers is crucial for future high-volume production. However, it also comes with challenges involving, in the case of SiN, decreasing thickness non-uniformity (NU) and handling the high mechanical stress [3].

Plasma enhanced chemical vapor deposition is considered to be a special form of chemical vapor deposition (CVD). The chemical deposition is supported only by a plasma. The plasma serves as an activation for the reaction of the reactive gases. The deposition temperatures are usually between 100 and 600 °C. Process temperature of ≤540 ° C.
