Abstract
This work proposes an automated semantic segmen-tation approach for high resolution scanning electron microscope images, which enables the detection of hardware Trojans and counterfeit integrated circuits. We evaluate state of the art segmentation approaches and leverage expert domain knowledge to propose a neural network architecture tailored for our use case. We further address the challenge of the limited availability of training images and evaluate which pre-trained encoder can be leveraged most effectively for the given use case. The proposed segmentation network uses expert domain knowledge to account for the importance of separating technology features on a fine-grain level by introducing a separate boundary stream. The test results compare our network to a baseline approach and to two state-of-the-art segmentation networks.

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
