摘要

The planar defect density of 3C-SiC can be reduced by growing it on undulant-Si substrates. However, specific stacking faults (SFs) remain, that expose the Si-face on the (001) surface. These residual SFs increase the leakage current in devices made with 3C-SiC. They can be eliminated using an advanced SF-reduction method called switch-back epitaxy (SBE) that combines polarity conversion with homoepitaxial growth. Vertical metal-oxide-semiconductor field-effect-transistors (MOSFETs) are fabricated on 3C-SiC with SBE, varying in size from a single cell with an area of (30 x 30) mu m(2) to 12,000 hexagonal cells on a (3 x 3) mm(2) chip. The MOSFET characteristics suggest that currents greater than 100 A are realistic for blocking voltages of 6001-1,200 V by increasing the number of cells with reduced cell-pitch. The combination of blocking voltage capability with a demonstrable high current capacity shows that 3C-SiC is well-suited for use in vertical MOSFETs for high- and medium-power electronic applications.
