Abstract
Abstract In order to improve the robustness of the ESD of the dual-direction silicon-controlled rectifier, a low doping deep well PB structure is proposed instead of the traditional high doping P+ structure. The ESD stress of the dual-direction SCR devices with deep well structure is discharged from inside and the lattice temperature of the device is low to avoid premature burnout of the device. The deep well PB structure on the surface of the device increases the parasitic resistance of the device and improve the conduction uniformity of the device. As the main conduction path of the device is located in NBL, the PB structure does not have a large influence on the sustain voltage. It is verified in a 0.25 μ m BCD process. With equivalent circuit and two-dimensional device simulation, the working mechanism is analyzed. According to the transmission line pulse test results and comparing with the data from traditional dual-direction SCR structure. The device’s fault current increases from 5.486 A to 8.13 A which is suitable for communication bus high voltage electrostatic discharge (ESD) 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
