Four Essential Engineering Topics
4H-SiC and 6H-SiC
Crystal polytype, Si/C-face orientation and doping must be specified for correct downstream compatibility, even when wafers share a nominal diameter.
Explore SiC →
C-Plane, A-Plane and R-Plane Sapphire
Crystal orientation influences machining and epitaxy. Specify orientation, offcut, polish and surface quality for the target fabrication process.
