WebJan 1, 2024 · Today 1200 V IGBTs with a chip thickness about 100–130 µm are common, 600 V IGBTs with around 70 µm. From theoretical limits for 1200 V blocking capability, chip thicknesses at about 80–90 µm should seem feasible, and for 600 V blocking capability it is about 45–50 µm. An epitaxial wafer (also called epi wafer, epi-wafer, or epiwafer ) is a wafer of semiconducting material made by epitaxial growth (epitaxy) for use in photonics, microelectronics, spintronics, or photovoltaics. The epi layer may be the same material as the substrate, typically monocrystaline silicon, or it may be a more exotic material with specific desirable qualities. Silicon epi wafers were first developed around 1966, and achieved commercial acceptance by th…
