WebA new method for the separation of threading screw dislocations (TSD) and threading edge dislocations (TED) in a 4H-SiC epitaxial layer is proposed by measurement of the etch pit angles. The etch pit angles of the TSDs and TEDs were 28±3 and 18±3°, respectively. In the case of etch pit depths within the epitaxial layer, the values were almost constant. WebJul 1, 2024 · This method makes it possible to observe BPD-TED conversion in a very shallow surface region of the SiC substrate. 80% of BPDs is converted to TEDs with a …
