Abstract
Abstract A critical requirement for low‐power microelectronics is the construction of logic circuits using complementary devices. In pursuit of low‐power solution‐processed thin film Complementary Metal Oxide Semiconductor (CMOS) circuits, significant research is expended toward producing the elusive p ‐type transistors. Beyond the challenges associated with processability and formulation complexity of existing metal halide solutions, they critically do not attain the electrical properties required to build productive devices. For the first time, this work describes high‐performance solution‐processed p ‐type thin film transistors developed using copper tin halide. Incorporating tin and high electronegativity halide species (Cl‐/F‐) improves CuI film morphology, stability, and electrical properties through copper/tin vacancy suppression, which results in high mobility, over 20 cm 2 Vs −1 , and low operating voltage Thin Film Transistors (TFTs). Furthermore, the p ‐type TFTs are able to be integrated with fully solution‐processed n‐type Indium Gallium Zinc Oxide (IGZO) TFTs in a highly transparent multilayer stack architecture. The monolithic 3D (M3D) CMOS design records inverter gains of 20 at V DD = 3V, demonstrating p ‐type devices fabricated using solution processing have the requisite high performance required for productive solution‐processed multilayer microelectronics.

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 it
