Abstract
A focused ion beam (FIB) is extensively used in various semiconductor processing applications, although the process is expensive and slow. In this paper we introduce an alternative technique using femtosecond laser pulse emitting directly from a laser oscillator. We demonstrated layer-by-layer removal in an IC circuit for inspection/failure analysis without damaging the underlying structures. There are two prime advantages of this technique. Firstly, the cost of the system is a fraction of that of a FIB machine. Secondly, the machine time is significantly shortened compared to that of a FIB process. Means to improve the accuracy, quality and resolution using a femtosecond laser pulse from the oscillator is discussed.

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
