Abstract

fetched live from OpenAlex

Tj control using single current source was successfully developed to replace Tcase control for testing microprocessor. Tj control uses diode junction temperature feedback whereas Tcase control uses case temperature (temperature at the die surface). In single current source Tj control, the single current source is employed to measure diode junction temperature. A simple circuitry is designed to supply a constant current to junction diode and its temperature-dependant forward-biased voltage is obtained and amplified before feeding into the PID controller. The thermocouple input signal in Tcase control is replaced with amplified voltage signal. An auto on-line diode characterization program is designed to determine mathematical relation between diode voltage and junction temperature, referred as the characteristic equation, before the start of every production lot. Its purpose is to minimize error in temperature measurement due to change in the characteristic equation which is different for different wafer lots and also is affected by changes in material and silicon fabrication process. Calibration accuracy is improved substantially with a new calibration jig.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
