A shorthand has been developed to catalogue the vast number of possible polytype crystal structures: Let us define three SiC bilayer structures (that is 3 atoms with two bonds in between in the illustrations below) and label them as A, B and C. Elements A and B do not change the orientation of the bilayer (except for possible rotation by 120°, which does not change the lattice and is ignored … Webformation process, a probable SiC oxidation layer formation mechanism in PECO is proposed. This work offers an alterna-tive approach to modify SiC wafers for efficiency promotion in CMP. 2 Principle and experiment of PECO 2.1 Principle of PECO Fig. 1 shows the SiC-solution interface and oxygen plasma formation process.
