Abstract
Nanoimprinting lithography was initiated as an alternative way to achieve nanoscale structures with high throughput and low cost. We have developed a UV-nanoimprint process to fabricate 34(34 crossbar circuits at 50 nm half-pitch (equivalent to a bit density of 10 Gbit/cm2) with single-layer structure. We devised a technique that exploits the opposite free energies of the mold and substrate surfaces to produce a very uniform resist film without any trap air. As the pitch size decreases, lift-off process with single-layer structure was difficult to define metal wires. Sixty-six by sixty-six crossbar structures with a half-pitch of 30 nm (equivalent to a bit density of 30 Gbit/cm2) were produced with bi-layer structure.

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
