AbstractLow-temperature homoepitaxial growth of 4H-SiC using halo-carbon precursors was further investigated to address the problems limiting increase of the growth rate of the defect-free epilayers at growth temperatures below 1300°C. Enhanced etching of Si clusters in the gas phase was achieved by adding HCl during the low-temperature growth. The effective Si/C ratio above the growth surface was increased as a result of reduced depletion of silicon vapor species by cluster condensation, which resulted in drastically improved epilayer morphology and significant increase of the growth rate. An intentional insitu nitrogen doping of epitaxial layers during 1300°C growth on Si and C faces revealed more than an order of magnitude higher nitrogen donor incorporation in the C-face epitaxial layers. Finally, a feasibility of selective epitaxial growth using low-temperature masking materials such as SiO2 was demonstrated.

Surface planarity and epi/SiO2 interface characteristics of selective epitaxial growth (SEG) and epitaxial lateral overgrowth (ELO), deposited at 800–950 °C/10 or 25 Torr, have been studied for micron-sized structures. SEG at 860 °C showed superior planarity and reduced ratio of facet width to epi thickness, compared to higher deposition temperatures. Data showed that epi/SiO2 interface defects are greatly reduced for structures parallel to (100) and/or by adding HCl to the source gas, compared to interfaces positioned at standard orientation (110) on a (100) substrate. The transition from SEG to ELO in view of the facet orientations will be discussed. To correlate structural with electrical data, n+/p diodes were fabricated on as-grown and polish planarized SEG. Leakage current values of approximately 100 nA/cm2 could be measured. These are comparable to similar n+/p junctions fabricated on conventional epi.
