Abstract
Measurement of Cu drifts in methylsilsesquiazane-methylsilsesquioxane dielectric films in the presence of an electric field was conducted using bias-temperature stress (BTS) and capacitor-voltage ( C V ) analysis as well as time dependent dielectric breakdown (TDDB) stress. The amount of Cu ions in the dielectric films can be estimated making use of the flatband voltage shift Δ V F B from the BTS. Comparing the flatband voltage measured by C V analysis with the leakage current integrated over time, it is found that the main content of the leakage current during BTS is ionic current that can be attributed to the drift of Cu and mobile ions. The Cu ions cause the leakage current during TDDB stress to increase. The drift rate of Cu in methylsilsesquioxane is lower than the reported values in polyarylene ether (PAE) and fluorinated polyimide (FPI), and larger than that in plasma enhanced chemical vapor deposition (PE C V D)-SiON.

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
