Results of the analytical modeling are shown in Fig. 4 for using both specific surface area ratio (irregular) and particle size ratio (spherical). The modeling results using the particle size ratio is larger than that using specific surface area ratio, as irregular particles tend to have a more loose packing due to the non-uniform packing structure [40].

In this article, we report a new cleaning method for silicon carbide (SiC) wafers. We found that the dipping treatment in hydrogen fluoride (HF) solution damages the SiC in the "RCA cleaning process", so we have designed a new cleaning method that does not use HF and reduced the cleaning process to three steps. The characteristic factor of this new …
