Abstract
An interdiffusivity model was established for SiGe interdiffusion under tensile or relaxed strain over the full Ge content (xGe) range (0 ≤ xGe ≤ 1), which is based on the correlations between self-diffusivity, intrinsic diffusivity, and interdiffusivity. It unifies available interdiffusivity models over the full Ge range and applies to a wider temperature range up to 1270 °C at the xGe = 0 end and to 900 °C at the high xGe = 1 end. Interdiffusion experiments under soak and spike rapid thermal annealing conditions were conducted to verify the model. Literature interdiffusion data under furnace annealing conditions were also used for the same purpose. The interdiffusivity model of this work has been implemented in major process simulation tools, and the simulation results showed good agreement with experimental data under furnace annealing and soak and spike rapid thermal annealing conditions. This work demonstrated a new approach in studying SiGe interdiffusion, which has the advantage of studying interdiffusion under non-isothermal annealing conditions.

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
