M09300 - SEMI M93 - Test Method for Quantifying Basal Plane Dislocation Density in 4H-SiC by X-Ray Diffraction Topography/Imaging StdPbc-0117 To avoid any disturbance ofBasal plane dislocations (BPDs) are detrimental for devices manufactured on 4H SiC substrates, especially for bipolar devices for power electronics. Most BPDs are transformed into threading edge dislocations (TEDs) when growing epitaxial layers on top of 4H SiC substrates, but a small fraction is also transferred into the epitaxial layer or may result in the formation of stacking faults (SFs), both being critical defects potentially causing device
