Figure 2: Etch rate of silicon carbide as a function of the CHF 3 flow rate. Figure 2 shows that the etch rate increases when the flow rate was increased from 40sccm to 60sccm. This suggests that ion boardment plays an important role in etch
2020/3/19· Palmour: Silicon has a bandgap of 1.1 electronvolts, and that is basically the definition of how much energy it takes to rip an electron out of the bond between two silicon atoms. So it takes 1.1 electronvolts to yank an electron out of that bond. Silicon carbide as a band gap of 3.2 electronvolts, and so it takes 3 times more energy.
