Abstract
Current surface modification chemistry of silicon nitride (Si 3 N 4 ) in the fabrication of micro/nano systems (MEMS/NEMS) mainly relies on multistep chemical processes, essentially consisting of a surface pretreatment and a challenging silanization procedure. Although direct modification of Si 3 N 4 surface has rarely been reported in the literature, here a simple surface functionalization strategy using diazonium chemistry in open air and at room temperature, which provides a practical solution to directly attach aminophenyl groups to pristine silicon nitride without altering its intrinsic properties, is described. These strongly grafted amine‐terminated groups are easily activated to become nuclei for initializing electroless nickel plating (autocatalytic nickel deposition). This electroless nickel plating of silicon nitride while avoiding the multiplicity and complexity of the process steps is ideal for its integration into a typical MEMS/NEMS process flow. In a possible integration scheme, due to its suitable properties, this nickel film serves as a conducting seed layer for the electrolytic deposition of copper to fill the microdevices, thereby avoids the use of typically employed expensive vacuum processes.

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
