Abstract
Semiconductor manufacturers and researchers have recently revealed that under specific bipolar gate switching conditions SiC MOSFETs exhibit parameter drift dynamics different from those typically observed in static qualification stress tests. In response to this finding, we present an approach for assessing the worst-case drift of data-sheet-relevant electrical parameters in a simple and transparent manner for a large variety of application profiles. We also introduce an empirical model that may explain the drift dynamics observed under gate switching stress; and discuss a recently developed interface characterization technique that has the potential to reveal the nature of point defects at the SiC/SiO 2 interface presumably related to the gate switching instability in SiC MOSFETs.

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
