Surface passivation of InGaAs for heterojunction bipolar transistor applications
Bibliographic record
Abstract
High-energy resolution x-ray photoelectron spectroscopy and photoluminescence have been used to investigate the properties of InGaAs (100) after different surface treatments using hydrofluoric acid (HF) and ultraviolet (UV)-ozone. The efficiency of these treatments was then evaluated using the leakage currents and the current gain of InGaAs/InP heterojunction bipolar transistors (HBTs). Although the effects on InGaAs material properties differ, they both improved the current gain of large area HBTs. Subsequent dielectric depositions induced a drastic degradation of the device characteristics, demonstrating the noncompatibility of these treatments with plasma-enhanced chemical vapor deposition (PECVD) processes. By appropriately combining the UV-ozone and HF treatments, a successful passivation can be achieved even under PECVD deposition.

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.
