4H-SiC Substrates

Single Crystal SiC (Silicon Carbide) is one of the high performance Semiconductor materials that is been used in the industry for its high thermal conductivity, high thermal budget, superior resistance to radiation properties. Low lattice mismatch to AlN and GaN makes it one of the first choice to high power, high frequency transistor applications. Moreover availability in market with small to large size gives flexibility to integrate these substrates in to existing fabrication lines. SiC finds large application areas in the Power and RF fields such as High Electron Mobility Transistors (HEMT) and MOSFETs.
