  • Patent number: 6952018
    Abstract: A semiconductor device includes a superlattice that, in turn, includes a plurality of stacked groups of layers. The device may also include regions for causing transport of charge carriers through the superlattice in a parallel direction relative to the stacked groups of layers. Each group of the superlattice may include a plurality of stacked base semiconductor monolayers defining a base semiconductor portion and an energy band-modifying layer thereon. Moreover, the energy-band modifying layer may include at least one non-semiconductor monolayer constrained within a crystal lattice of adjacent base semiconductor portions. Accordingly, the superlattice may have a higher charge carrier mobility in the parallel direction than would otherwise be present.

  • Publication number: 20050184286
    Abstract: A semiconductor device includes a substrate, and at least one MOSFET adjacent the substrate. The MOSFET may include a superlattice channel that, in turn, includes a plurality of stacked groups of layers. The MOSFET may also include source and drain regions laterally adjacent the superlattice channel, and a gate overlying the superlattice channel for causing transport of charge carriers through the superlattice channel in a parallel direction relative to the stacked groups of layers. Each group of the superlattice channel may include a plurality of stacked base semiconductor monolayers defining a base semiconductor 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 semiconductor portions so that the superlattice channel may have a higher charge carrier mobility in the parallel direction than would otherwise occur.

  • Publication number: 20040262594
    Abstract: The present invention relates to controlling the properties of semiconductor materials at the atomic or molecular level to achieve improved performance within semiconductor devices. Further, the invention relates to the identification, creation, and use of improved materials for use in the conduction paths of semiconductor devices. More specifically, the inventors have identified materials or structures having energy band structures in which the average curvature of the conduction and valence bands and band edges is substantially greater than the average curvature of conduction and valence bands in single crystal silicon. This substantially greater curvature corresponds to lower effective mass and, hence, greater carrier mobility.
