Development of Embedded Redistribution Layer-Based Silicon Interposer for 3-D Integration
Bibliographic record
Abstract
Silicon interposers that are typically composed of redistribution layers (RDLs) and through-silicon vias have become a popular alternative approach to achieve 3-D integration. However, issues including the long metallization duration and the risk of unacceptable interfacial resistance or even disconnection are prohibiting their wider adoption. In this paper, by substituting RDLs with conductive polymer-filled trenches at the bonding interface, a silicon interposer architecture with faster fabrication speed and better interfacial connection was developed. Ag-based and carbon-based (C-based) conductive polymers with different viscosities were tested under varying vacuum suction conditions. It was found that the filling ratio would increase more efficiently with the driving pressure. Besides, measurements indicated the average resistance of channels filled with Ag-based conductive polymers was in the range of 40-55 Ω. Furthermore, their resistivity stability and bonding strength to Cu and Al had proven to be promising during the temperature increase.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
