| Research Abstract |
Silicon carbide (SiC) is a promising next-generation semiconductor material for high-temperature, high-frequency and high-power device applications due to its excellent properties, such as good thermal conductivity, good carrier mobility and high chemical stability. However, SiC substrates are relatively difficult to machine because of their mechanical hardness and marked chemical inertness.
The purpose of this research is to develop the high precision and high efficiency planarization method for SiC substrate indispensable to production of a next-generation semiconductor device. In this study, we have proposed a novel planarization method for a SiC surface and GaN surface utilizing the OH radicals generated from an Fe catalyst and H2O2 solution, and demonstrated the effectiveness and impact of the proposed method. Finally, we have succeeded in planarizing overall 2-inch SiC substrate and succeeded in smoothing GaN surface.
