Abstract
This thesis presents the design of a prototype chip of a 3D IC made in the Tezzaron Process.As this work is the first of its kind at a Canadian University, this thesis is focused on the characterization of the one of the key components of this technology, that being, the Through-Silicon Via or TSV for short.The TSV is modeled as a lumpedequivalent RC circuit, whereby embedded instruments have been constructed to measure the R and the C of a TSV.Specifically, a Kelvin four-point probe has been devised to measure the series resistance of a TSV and several versions of a parasitic capacitance meter has been constructed to measure the effective shunt capacitance of a TSV.One approach to measuring the shunt capacitance makes use of a frequency-based approach whereby the frequency of two ring oscillators, one loaded by a TSV, the other left opened, are measured and used to predicted the capacitive load difference.The other approach makes use of a charge-based method whereby the average difference in the amount of charged transferred in any one charging cycle is measured using a current meter.To ease the measurement control and data capture, an analog JTAG test bus was developed and used to extract the test data in a manner that is compatible with that used in the semiconductor industry.An extension to the JTAG analog boundary scan cell is proposed that reduces the silicon overhead required when used in a 3D-IC.

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
