How does plasma enhance CVD?

Plasma Enhanced Chemical Vapor Deposition (PECVD) is a process by which thin films of various materials can be deposited on substrates at lower temperature than that of standard Chemical Vapor Deposition (CVD). Plasma-Therm offers PECVD technology on the Vision Series and VERSALINE platforms.

What is plasma Activated chemical vapor deposition?

Plasma-enhanced chemical vapor deposition (PECVD) is a chemical vapor deposition process used to deposit thin films from a gas state (vapor) 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.

What is the difference between CVD and PECVD?

Plasma-enhanced chemical vapor deposition is a variant of CVD; however, it uses plasma energy instead of only thermal energy to deposit thin films. PECVD can use various materials as coatings, including metals, oxides, or silicon, which may offer more flexibility than CVD.

Why is PECVD used?

Applications. PECVD is used in nanofabrication for deposition of thin films. PECVD deposition temperatures are between 200 to 400°C. It is used rather than LPCVD or thermal oxidation of silicon when lower temperature processing is necessary due to thermal cycle concerns or material limitations.

What is plasma-enhanced ALD?

A plasma-enhanced atomic layer deposition (PE-ALD) system enables the conformal fabrication of thin films of various materials with atomic-scale control. ALD is a controlled chemical vapor deposition process that utilizes gas precursors to deposit a film one atomic layer at a time.

Is Pecvd conformal?

Conformality or Step Coverage ALD, TEOS, HTO, and thermal oxide are very conformal. LTO, PECVD, sputtering, and evaporation are much less conformal.

What is Mocvd process?

MOCVD is a process for manufacturing complex semiconductor multilayer struc- tures used in electronic or optoelectronic components such as LEDs, lasers, high- speed transistors or solar cells.
