Abstract
In this paper, we report on a novel direct wafer bonding technique; Si (111) wafers to polycrystalline silicon carbide carrier wafers. The purpose of this work is to provide a platform for 3C-SiC epitaxial growth above the wafer bonded Si (111) wafers. We have demonstrated reduced wafer bow, confirmed by optical microscopy together with a digital camera. 3C-SiC epitaxial layers have been grown by conventional chemical vapor deposition techniques above Si/SiC structures. All of these 3C-SiC epitaxial layers are highly crystalline in nature. In the future, the realization of thick, bow-free 3C-SiC layers suitable for power device fabrication is achievable.
