A New Foundry-Based Open-Gate Junction Field-Effect Transistor (OG-JFET) as Electronic Sensing Platform (ESP) for Life Science Applications
Bibliographic record
Abstract
An electronic sensor platform based on ionsensitive open-gate junction field-effect-transistors (OG-JFET) is introduced for life science applications. OG-JFET is fabricated by an established and mass-producible method. A thin layer (1.6 µm) of p-type silicon is epitaxially grown on thick (450 µm) n-type silicon to create a vertical p-n junction. The p-type layer serves as the main channel with two ohmic contacts as the source and drain. OG-JFET in our design showed a sensitivity of 52.12 mV/pH and 16 mV hysteresis with a 3 µA/hour drift rate. Also, a COMSOL Multiphysics model is introduced for efficient design of OG-JFET.Based on the experimental results and simulation studies, here we present for the first-time biosensing applications using the OG-JFET multi-user platform.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
