Sic sapphire
WebThe use of silicon carbide is rapidly increasing for high voltage and high-power components, including Wide Band Gap (WBG) semiconductors. Scribing techniques include trench-ablation, and also a proprietary internal material scribe that results in low debris and very easy die breaking and separation. Figure shows 100 μm SiC scribed at 300 mm/sec. WebThese works have demonstrated the first growths of hexagonal and cubic SiC on sapphire and 6H-SiC or silicon, respectively. However, few details have been given concerning the AlN microstructure and the possible interplay between the materials, except for the presence of Al autodoping in SiC during the growth process [ 10 ].
