Abstract
The input/output (I/O) pins of an industry-level fluorescent optical fiber temperature sensor readout circuit need on-chip integrated high-performance electro-static discharge (ESD) protection devices. It is difficult for the failure level of basic N-type buried layer gate-controlled silicon controlled rectifier (NBL-GCSCR) manufactured by the 0.18 µm standard bipolar-CMOS-DMOS (BCD) process to meet this need. Therefore, we propose an on-chip integrated novel deep N-well gate-controlled SCR (DNW-GCSCR) with a high failure level to effectively solve the problems based on the same semiconductor process. Technology computer-aided design (TCAD) simulation is used to analyze the device characteristics. SCRs are tested by transmission line pulses (TLP) to obtain accurate ESD parameters. The holding voltage (24.03 V) of NBL-GCSCR with the longitudinal bipolar junction transistor (BJT) path is significantly higher than the holding voltage (5.15 V) of DNW-GCSCR with the lateral SCR path of the same size. However, the failure current of the NBL-GCSCR device is 1.71 A, and the failure current of the DNW-GCSCR device is 20.99 A. When the gate size of DNW-GCSCR is increased from 2 µm to 6 µm, the holding voltage is increased from 3.50 V to 8.38 V. The optimized DNW-GCSCR (6 µm) can be stably applied on target readout circuits for on-chip electrostatic discharge protection.

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 it
