WebPECVD processing allows deposition at lower temperatures, which is often critical in the manufacture of semiconductors. The lower temperatures also allow for the deposition of organic coatings, such as plasma polymers, that have been used for nanoparticle surface functionalization. [5] WebAbstract. This chapter presents a short review of plasma-enhanced chemical vapor deposition (PECVD) of non-oxide ceramics. A brief discussion of glow discharge plasmas as used in PECVD is presented first. This discussion provides a practical understanding of the processes and characteristic chemistry involved in PECVD.
