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 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.
