PECVD Plasma Enhanced Chemical Vapor Deposition

We have three PECVD's here at DANCHIP. They can all be used to deposit Silicon oxides and Silicon nitrides with or without dopants of Boron, Phosphorus and Germanium. PECVD1 and PECVD3 are used for silicon based processing where as PECVD2 is dedicated deposition on III-V materials. PECVD1 is the cleanest system where as PECVD3 is allowed to use with substrates with small abouts of metal on. See the precise rules in the equipment manuals which are uploaded in LabManager.

PECVD is a chemical vapor deposition process that applies a plasma to enhance chemical reaction rates of reactive spices. PECVD processing allows deposition at lower temperatures, which is often critical in the manufacture of semiconductors.

All though PECVD1, 2 and 3 are very similar you should not expect to transfer a recipe between the systems and get the same exact same result.
