WebHeating silicon carbide (SiC) to high temperatures (> 1100 °C) under low pressures (~10 −6 torr) reduces it to graphene. This process produces epitaxial graphene with dimensions dependent upon the size of the wafer. The polarity of the SiC used for graphene formation, silicon- or carbon-polar, highly influences the thickness, mobility and carrier density. WebThe Probus-SiC™ series is an automated SiC epitaxial film growth equipment developed by incorporating state-of-the-art technologies such as vacuum technology, transfer technology and high-temperature control technology that TEL has cultivated in the semiconductor manufacturing equipment market. We introduced the most advanced …
WebSiC epitaxy with growth rates exceeding 50 µm/hr is highly desired. Commercial SiC CVD processes typically use silane and light hydrocarbons, such as propane or ethylene, diluted in hydrogen as a carrier gas. While growth rates higher than the usual 6-7 um/hr [5] may be achieved by increasing precursor flow, this typically leads Web15 de dez. de 2005 · High growth rates (>30 μm/h) of 4H–SiC epitaxial layers using a horizontal hot-wall CVD reactor @article{Myers2005HighGR, title={High growth rates (>30 $\mu$m/h) of 4H–SiC epitaxial layers using a horizontal hot-wall CVD reactor}, author={R.
