On the Origin of Anomalous Off–Current Under Hot Carrier Stress in p-Channel DDDMOS Transistors With STI Structure
Bibliographic record
Abstract
This letter investigates the abnormal off-current behavior induced by hot carrier stress (HCS) in p-channel double diffused drain metal-oxide-semiconductor transistors with a shallow trench isolation (STI) structure. According to ISE-TCAD simulation, the electric field at the drain-side corners of the high-voltage n-well (HVNW) adjacent to the STI trench is stronger than the electric field in the channel center in width direction. Moreover, because a nitride layer acts as a buffer in STI, the electrons generated by impact ionization at the corners of the HVNW can be easily trapped in the nitride layer or at the liner oxide/nitride layer interface. Furthermore, the extension of electron trapping in STI from drain to source during HCS forms the off-current conductive path. Based on the charge pumping measurements at different operation conditions, this path formation is further demonstrated by the comparisons of charge pumping measurements between initial state and after HCS.

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.
