Two-Dimensional Quantum-Mechanical Modeling and Simulation of Strained-Si Fin Field Effect Transistor (FinFET) on SiGe-On-Insulator
Bibliographic record
Abstract
A strained-Si fin field effect transistor (SSFinFET) on SiGe-on-insulator is modeled and using two-dimensional Schrödinger and Poisson equations quantum-mechanically simulated in a self-consistent manner. The quantum electron concentration in an SS fin is then obtained using a two-dimensional Schrödinger equation. The field-dependent mobility in SS fin is calculated using the doping-dependent mobility which considered strain and velocity overshoot effects. These effects give rise to an enhancement in the drain current of SSFinFET by up to 25% compared with the conventional FinFET using relaxed Si-on-insulator (RSFinFET). For the gate length 1.5 times longer than fin width, the drain induced barrier lowering (DIBL) and subthreshold swing are below 0.1 V/V and 60 mV/dec, respectively, regardless of whether Si-fin experiences a strain. These results indicate that the ratio of gate length to fin width should be above approximately 1.5 to suppress short channel effects and DIBL in both SSFinFET and RSFinFET.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
