Stability of nc-Si:H TFTs With Silicon Nitride Gate Dielectric
Bibliographic record
Abstract
We report the fabrication and characterization of bottom-gate and top-gate nanocrystalline silicon (nc-Si:H) thin-film transistors (TFTs) with amorphous-silicon nitride (a-SiNx:H) as the gate dielectric. The devices were fabricated using standard 13.56-MHz plasma-enhanced chemical vapor deposition at 240 degC. Here, the same 80-nm nc-Si:H channel, 300-nm a-SiNx:H gate dielectric, and 60-nm n+nc-Si:H ohmic contact layers were used in both TFT structures. We analyzed the effects of gate configuration on TFT performance and, in particular, the electrical stability. The stability tests were carried out at a gate bias stress in the range from 20 to 40 V. The nc-Si:H TFTs demonstrated much better threshold-voltage (VT) stability compared with the amorphous-silicon (a-Si:H) counterparts, offering great promise for applications in active-matrix organic light-emitting diode (AMOLED) displays

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
