A Study of Process Interruptions during Pre- and Post-Buffer Layer Epitaxial Growth for Defect Reduction in 4H SiC Open
We perform epilayer growth where the process is interrupted (in situ) during post and pre buffer layer growth at a reduced temperature. Process interrupted during post buffer layer growth demonstrates significant reduction in basal plane d…
