A Wide Dynamic Range CMOS Image Sensor with Improved Heat-Resistance and Image Quality at High Temperatures
Bibliographic record
Abstract
A 1/4-inch VGA wide-dynamic-range complementary metal oxide semiconductor (CMOS) image sensor with resistance to high temperatures has been developed using a lateral overflow capacitor in a pixel, a very low dark-current front-end-of-line (VLDC FEOL) , and either an inorganic cap layer on an on-chip-micro-lens (OCML) or a metal hermetically sealed package to suppress the degradation of the spectra response of the OCML and color filter. The dark current level was reduced to 25e-/sec/pixel at 60°C. Sensor chips with no cap and ones with the inorganic cap layer on the OCML were assembled into either a metal hermetically sealed package or a conventional package. The chips with the inorganic cap layer and the ones with the metal hermetically sealed package showed no significant degradation of the spectra response in any of the R/G/B pixels even after a thermal stress test at 150°C. Improved image sensing performances were observed up to 85°C, and the dynamic range was extended to 94dB.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
