Simulation Studies on Giant Step Bunching Accompanying Trapezoid-Shape Defects in 4H-SiC Epitaxial Layer

Article Preview

Abstract:

Trapezoid-shape (T-S) defects on epilayer surfaces, which include two kinds of the giant step bunching (GSB), are one of killer defects for MOSFETs. We have investigated the generation mechanism of the two GSBs using "step kinetics simulator" we developed. The simulator has reproduced the behavior of the GSBs. Based on results from the simulation, we have discussed the generation mechanism of the two GSBs.

[7] The generation of U- and D-GSB is strongly suggested to be related to a defect under the U-GSB. The cluster effect causes GSB regardless of the existence of defects. To estimate only the effect of the defects, therefore, we do not consider the cluster effect.
