Selective wet-etch processing of optically transparent flexible InGaZnO thin-film transistors
Bibliographic record
Abstract
Flexible InGaZnO (IGZO) thin-film transistors (TFTs) having more than 85% optical transparency in the visible regime were fabricated on polyethylene naphthalate substrates using a selective wet etching process at a maximum temperature of 150 °C. An etch selectivity of >15 was used to pattern Al-doped ZnO S/D contacts on IGZO channel layers in a back-channel etch process. Flexible IGZO TFTs exhibited a field-effect mobility of ∼9.5 cm2/V s, threshold voltage of ∼4 V, subthreshold swing of 0.5 V/decade, and an Ion/Ioff ratio of ∼107. Similar I-V characteristics were measured for flexible TFTs under flat, tensile and compressive strain while a 3.8 V threshold voltage shift was observed after application of a dc gate-bias for 3600 s with the TFTs operating in the linear regime.

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.
