Abstract
The micro/nanofabrication industry’s transition from physically deposited dielectric films toward relatively inexpensive insulating polymeric materials faces a challenging metallization step in progression. In this work, we demonstrate a metallization scheme constituting simple and completely aqueous chemical steps─from Si passivation to metallization. We first propose a versatile diazonium-based electrochemical process to graft an in situ aminated poly(methyl methacrylate) (PMMA) liner onto Si microfeatures with high step-coverage. These amine-terminated groups functionalize the grafted PMMA-like liner with palladium chloride complex activators and allow direct autocatalytic deposition of Ni–B film while avoiding any further amination step as conventionally required for polymeric surfaces. The obtained Ni–B film exhibiting high uniformity, strong adhesion to the polymer film, and excellent step-coverage from the top, sidewall, and bottom of the microstructures fulfills all requirements of a conducting seed layer for the subsequent electrolytic deposition of copper.

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
