                          Silicon carbide (SiC) ceramics have become increasingly important in the semiconductor industry due to their exceptional thermal, mechanical, chemical, and electrical properties. Beyond their role as wide-bandgap semiconductor substrates for power devices, SiC ceramics are widely used in semiconductor manufacturing equipment, packaging, and thermal management systems. This article provides a scientific overview of SiC ceramics
