Abstract (en)

[origin: WO2007130973A1] A semiconductor device may include at least one metal oxide field-effect transistor (MOSFET). The at least one MOSFET may include a body, a channel layer adjacent the body, and a dopant blocking superlattice between the body and the channel layer. The dopant blocking superlattice may include a plurality of stacked groups of layers. Each group of layers of the dopant blocking superlattice may include a plurality of stacked base semiconductor monolayers defining a base semiconductor portion, and at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions.
