WebDeep trench / multi-epi: deep trench technology is improving, but is still too expensive. The technology used for Super Junction MOSFET is of two types. The first one, developed by Infineon, uses a series of epitaxies and doping to create a locally doped "island" in the epi-layer. The doped region then diffuses and creates an n-doped pillar.
