Abstract
Abstract Gallium focused ion beams (Ga-FIB) have been used historically in the semiconductor industry for failure analysis, as well as circuit edit. However, in spite of the best of these efforts, as integrated circuit dimensions continue to shrink, Ga-FIB induced processes are being driven to their physical limits. The main purpose of this paper is to report the helium and neon ion beams' induced chemistry, including metal deposition, dielectric deposition, and chemically enhanced etching. Two simple examples are shown as proofs of concept demonstrating gas field ion source (GFIS) development for circuit edit applications. The paper summarizes the general utility of helium and neon ion beams for metal deposition, dielectric deposition, and sputtering and etching processes, and discusses some of the technical challenges associated with current GFIS technology. Using GFIS ion beams, it has been observed that the top and buried metal lines can be cut precisely and then reconnected.

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
