Abstract
Low throughput is the major drawback for electron beam lithography. Chemically amplified resists that have high sensitivity are often used to keep the exposure time within practical limit. In this Letter the authors show that the popular non-chemically amplified electron beam resist ZEP-520A can achieve 2.6 µC/cm2 sensitivity when using methyl ethyl ketone:methyl isobutyl ketone developer and 5 keV exposure, though at the cost of reduced contrast compared to standard developers xylene, n-amyl acetate or hexyl acetate. The achievable resolution was found to depend strongly on the resist's adhesion to the substrate or under-layer and thus obtained 40 nm half-pitch resolution using ZEP resist spun on a layer of anti-reflection coating that was treated by oxygen plasma.

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
