N-type SiC on Si Compound Wafer abstract

N-type silicon carbide (SiC) on silicon (Si) compound wafers have garnered significant attention due to their promising applications in high-power and high-frequency electronic devices. This study presents the fabrication and characterization of N-type SiC on Si compound wafers, emphasizing their structural, electrical, and thermal properties. Utilizing chemical vapor deposition (CVD), we successfully grew a high-quality N-type SiC layer on a Si substrate, ensuring minimal lattice mismatch and defects. The structural integrity of the compound wafer was confirmed through X-ray diffraction (XRD) and transmission electron microscopy (TEM) analyses, revealing a uniform SiC layer with excellent crystallinity. Electrical measurements demonstrated superior carrier mobility and reduced on-resistance, making these wafers ideal for next-generation power electronics. Additionally, the thermal conductivity was enhanced compared to traditional Si wafers, contributing to better heat dissipation in high-power applications. The results suggest that N-type SiC on Si compound wafers hold great potential for integrating high-performance SiC-based devices with the well-established silicon technology platform.
