    摘要: A method (and semiconductor device) of fabricating a TFET device provides a source region having at least a portion thereof positioned underneath a gate dielectric. In one embodiment, the TFET includes an N+ drain region and a P+ source region in a silicon substrate, where the N+ drain region is silicon and the P+ source region is silicon germanium (SiGe). The source region includes a first region of a first type (e.g., P+ SiGe) and a second region of a second type (undoped SiGe), where at least a portion of the source region is positioned below the gate dielectric. This structure decreases the tunneling barrier width and increases drive current (Id).

    摘要: Methods (and semiconductor substrates produced therefrom) of fabricating (n−1) SDOI substrates using n wafers is described. A donor substrate (e.g., silicon) includes a buffer layer (e.g., SiGe) and a plurality of multi-layer stacks formed thereon having alternating stress (e.g., relaxed SiGe) and strain (e.g., silicon) layers. An insulator is disposed adjacent an outermost strained silicon layer. The outermost strained silicon layer and underlying relaxed SiGe layer is transferred to a handle substrate by conventional or known bonding and separation methods. The handle substrate is processed to remove the relaxed SiGe layer thereby producing an SDOI substrate for further use. The remaining donor substrate is processed to remove one or more layers to expose another strained silicon layer. Various processing steps are repeated to produce another SDOI substrate as well as a remaining donor substrate, and the steps may be repeated to produce n−1 SDOI substrates.
