Novel ultra-low power RF Lateral BJT on SOI-CMOS compatible substrate
Bibliographic record
Abstract
This work presents a novel ultra-low power RF LBJT on SOI. The fabrication process relies on polysilicon side-wall-spacer (PSWS) to self-aligned the base contact to the intrinsic base in the 100 nm range. The fabricated LBJTs exhibits superior Johnson's product (f <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">τ</inf> x BV <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">CEO</inf> ) in the range between 190-300 GHz.V. The f <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">max</inf> of the optimal device reaches 46 GHz at collector current density of only 0.15 m/μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . Both figure-of-merit are in-line with advanced SiGe-HBT device, and superior than previously published data on lateral BJTs. This LBJT is built on SOI-CMOS compatible substrate, and is an ideal candidate for SOI-BiCMOS integration for RF and mixed-signal SoC.

How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
