ABSTRACT:
A dual gate thin film or SOI MOSFET device having a sufficiently thin body thickness with one or more semiconductor channel layer(s) sandwiched by semiconductor layers having a different energy band structure to automatically confine carriers to the channel layer(s) without the need for channel grading or modulation doping. Preferred embodiments employ strained layer epitaxy having Si/SiGe/Si or SiGe/Si/SiGe semiconductor layers.
