The PVT growth is used to manufacture boules from which wafers are fabricated.
The close space PVT (CS-PVT) is a version for thin film growth on wafers.
The CS-PVT has several advantages, such as lower cost and being used to explore silicon carbide approaches for emerging technologies.
Both PVT and CS-PVT use the same hardware equipment. The difference is in the hot-zone design.
