Abstract
A challenge to most 3D integration approaches is the deposition of the Through-Silicon-Via (TSV) dielectric layer. A TSV is traditionally electrically insulated from the silicon substrate by a thin SiO 2 film. As TSV aspect ratio gets higher, conformal SiO 2 dielectric deposition becomes much more challenging. Alchimer has proposed as dielectric, the use of a highly conformal organic (poly-4-vinylpyridine, P4VP) as dielectric, electrografted through electrochemical reduction of diazonium salts in aqueous media. Surface cleaning prior to electrografting process is a challenge, especially in via last approach. Moreover, the thermomechanical behavior of P4VP coated TSVs remains unknown. This information is most relevant for the layout optimization of 3D integrated microsystems. We will discuss the TSV surface preparation challenge prior to the electrografting process and present the first measurements of the stress induced in the silicon substrate around TSV insulate by P4VP.

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
