Growth and properties of diamond films prepared on 4-inch substrates by cavity plasma systems
Babčenko, Oleg ; Potocký, Štěpán ; Aubrechtová Dragounová, Kateřina ; Szabó, Ondrej ; Bergonzo, P. ; Rezek, B. ; Kromka, Alexander
We compare two microwave (2.45 GHz) plasma systems with ellipsoidal and multimode clamshell cavity for diamond synthesis by chemical vapor deposition. We use H2/CH4/CO2 gas mixture for diamond film deposition on Si <100> wafers. Both systems are capable of high pressure (up to 20 kPa) operation and high growth rates (several µm/h). We compare the cavity systems from the point of diamond quality (Raman shift measurement), substrate size (2” versus 4”) and grown film homogeneity together with surface morphology (SEM), deposition rate and parasitic doping levels (photoluminescence).
