Abstract
Wafers including a diamond layer and a semiconductor layer having III-Nitride compounds and methods for fabricating the wafers are provided. A first SiC layer is formed on a silicon substrate, and using a carbon containing gas, a surface of the first SiC layer is carbonized to form carbon particles on the SiC layer. Then, a diamond layer is grown on the carbonized surface, where the carbon atoms act as seed particles for growing the diamond layer. A second SiC layer is formed on the diamond layer and a semiconductor layer having III-Nitride compounds is formed on the second SiC layer. Then, the silicon substrate and the first SiC layer are removed.
