Photolithographically defined polythiophene organic thin-film transistors
Bibliographic record
Abstract
A photolithography process for the fabrication of organic thin-film transistor (OTFT) and integrated circuits will be presented. Fully encapsulated polythiophene OTFTs in the top-gate, bottom-gate, and dual-gate configurations have been demonstrated using this approach. Photolithography steps are incorporated for the definition of gate electrodes and source/drain contacts, isolation of transistors, and formation of vias and interconnects. These steps are vital to achieve device integration and to realize organic integrated circuits for applications such as flat panel displays and radio-frequency identification tags. The fabrication process is compatible with various substrates (e.g., glass and plastic), and enables the realization of discrete transistors and OTFT-based circuits through consecutive photolithographic steps and a tailored etch recipe for patterning of the polymer film. This article will provide a detailed examination of the fabrication approach, analyze the electrical performance of various photolithographically defined regioregular poly(3-hexylthiophene) OTFT structures, and explore the device and circuit advantages of the photolithography strategy.

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.
