摘要： Disclosed are embodiments of an asymmetric field effect transistor structure and a method of forming the structure in which both series resistance in the source region (Rs) and gate to drain capacitance (Cgd) are reduced in order to provide optimal performance (i.e., to provide improved drive current with minimal circuit delay). Specifically, different heights of the source and drain regions and/or different distances between the source and drain regions and the gate are tailored to minimize series resistance in the source region (i.e., in order to ensure that series resistance is less than a predetermined resistance value) and in order to simultaneously to minimize gate to drain capacitance (i.e., in order to simultaneously ensure that gate to drain capacitance is less than a predetermined capacitance value).

摘要： Disclosed are embodiments of a field effect transistor (FET) and, more particularly, a fully-depleted, thin-body (FDTB) FET that allows for scaling with minimal short channel effects, such as drain induced barrier lowering (DIBL) and saturation threshold voltage (Vtsat) roll-off, at shorter channel lengths. The FDTB FET embodiments are configured with either an edge back-gate or split back-gate that can be biased in order to selectively adjust the potential barrier between the source/drain regions and the channel region for minimizing off-state leakage current between the drain region and the source region and/or for varying threshold voltage. These unique back-gate structures avoid the need for halo doping to ensure linear threshold voltage (Vtlin) roll-up at smaller channel lengths and, thus, avoid across-chip threshold voltage variations due to random doping fluctuations. Also disclosed are method embodiments for forming such FETs.
