METHOD FOR MAKING A SEMICONDUCTOR DEVICE INCLUDING A SUPERLATTICE AND ADJACENT SEMICONDUCTOR LAYER WITH DOPED REGIONS DEFINING A SEMICONDUCTOR JUNCTION

摘要

A method for making a semiconductor device may include forming a superlattice comprising a plurality of stacked groups of layers. Each group of layers of the superlattice may include a plurality of stacked base silicon monolayers defining a base silicon portion and an energy band-modifying layer thereon. The energy band-modifying layer may include at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base silicon portions. The method may further include forming a semiconductor layer adjacent the superlattice and comprising at least one first region therein including a first conductivity type dopant. At least one second region may be formed in the superlattice including a second conductivity type dopant to define, with the at least one first region, at least one semiconductor junction.
