Flash Lamp Annealed LTPS TFTs with ITO Bottom-Gate Structures
Bibliographic record
Abstract
A study on bottom-gate PMOS TFTs built on flash lamp annealed polycrystalline silicon is presented. As an alternative to top-gate devices, bottom-gate TFTs offer potential benefits in dielectric-semiconductor interface quality due to process integration details of crystallization and defect passivation. Indium Tin Oxide was used as the gate electrode material due to its attractive optical and electrical properties, thermal stability, and compatibility with the FLA process. Details of an experimental design used to investigate combinations of FLA and furnace annealing for a-Si crystallization and dopant activation processes will be discussed. ITO Bottom-gate TFTs fabricated with FLA crystallization followed by boron ion implantation and furnace activation exhibited superior electrical characteristics in comparison to other treatments. A comparison of electrical characteristics measured on bottom-gate and double-gate devices is used to develop an interpretation of defect effects and provide a qualitative assessment of interface states.

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.
