# Fabrication Variability Analysis

Focused ion beam milling variance is no longer predicted as a single deterministic result: a conditional diffusion model learns the statistical distribution of process outcomes given the input design, yielding distributional predictions of edge morphology, linewidth variation, and defect probability.
