Abstract

fetched live from OpenAlex

Abstract Planar s plit‐ g ate MOSFETs (SG‐MOSFETs) are promising in high‐frequency power applications due to the fast turn on/off speeds and low switching loss. However, SG‐MOSFETs suffer from crowded electric field at the edge of the split poly‐Si gate, resulting in the degradation of the blocking voltage and the gate oxide reliability. This issue becomes more critical in 4H‐SiC MOSFETs due to the high critical breakdown electric field. In this work, a new 1.2‐kV 4H‐SiC SG‐MOSFET structure is proposed and investigated by TCAD simulation. The proposed structure features a s ource metal f ield p late located between two adjacent split poly‐Si gates (termed SFP‐SG‐MOSFET). In the blocking state, the source metal field plate reduces the peak electric field at the edge of the poly‐Si gate. The maximum electric field in the gate oxide of the proposed SFP‐SG‐MOSFET is reduced by 52.8% compared with the SG‐MOSFET, for reliable operation. The reverse transfer capacitance ( C rss ) and gate‐to‐drain charge ( Q gd ) are reduced by 56.4% and 61.8% compared with SG‐MOSFETs, respectively. Therefore, the high‐frequency figure‐of‐merits (HF‐FOM) [ R on × C rss ] and [ R on × Q gd ] are improved by 2.2 times and 2.5 times, respectively.

Teacher imitation

Not 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.
