Abstract
Gate-first integration of band-edge (BE) high-κ/metal gate nFET devices with dual stress liners and silicon-on-insulator substrates for the 45nm node and beyond is presented. We show the first reported demonstration of improved short channel control with high-κ/metal gates (HK/MG) enabled by the thinnest T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">inv</sub> (≪12Å) for BE nFET devices to-date, consistent with simulations showing the need for ≪14Å T <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">inv</inf> at Lgate≪35nm. We report the highest BE HK/MG nFET Idsat values at 1.0V operation. We also show for the first time BE high-κ/metal gate pFET's fabricated with gate-first high thermal budget processing with thin T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">inv</sub> (≪13Å) and low Vts appropriate for pFET devices. The reliability in these devices was found to be consistent with technology requirements. Integration of high-κ/metal gate nFET's into CMOS devices yielded large SRAM arrays.

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 it
