The dielectric properties have been determined for stoichiometric amorphous hydrogenated silicon carbide (a-SiC:H) films grown by means of the plasma-enhanced chemical vapor deposition (PECVD) technique. The dielectric constant, dielectric loss, breakdown voltage, and current–voltage (I–V) characteristics of the a-SiC:H PECVD films were systematically determined for various film
The deposition of the hydrogenated microcrystalline silicon carbide (μc-SiC:H) layers was carried out in a conventional rf (13.56 MHz) capacitive type plasma enhanced chemical vapour deposition (PECVD) system at a substrate temperature of 200 C from the mixture of silane, methane and argon at flow rates of 1.5 sccm, 1.5 sccm and 97 sccm respectively, with rf power density of 80 mW/cm 3 and
Beryllium oxide, aluminum nitride, alumina, silicon carbide, and silicon ni-tride have a permittivity higher than thoses of most organic materials [16,17]. Silicon carbide is a semiconductor and is often coined with BeO to obtain a low-loss sub-strate. Beryllium
Silicon carbide is a compound of silicon and carbon with the chemical formula SiC. It occurs in the extremely rare mineral moissanite. Silicon carbide grains are bonded together by sintering to form hard ceramics that are used in appliions requiring high endurance.
