An nMOS Static ESD Power Supply Clamp With Thyristor Delay Element and 180 pA Leakage in 65 nm CMOS Technology
Bibliographic record
Abstract
Electrostatic discharge (ESD) is a well-known problem in integrated circuits (ICs) that impacts the reliability, yield, and cost of the ICs. In this paper, a low-leakage, static ESD clamp is proposed in 65-nm CMOS technology. CMOS thyristor was added as a delay element to the conventional diode triggered static clamp to improve its on time during the ESD stress, while the thick oxide transistors were used to reduce the leakage under normal operating conditions. The proposed clamp was characterized at different process corners under ESD stresses. The transmission-line pulse measurement results show that the clamp is capable of handling 3.21 A of current, and has 180 pA as the leakage current at room temperature. Measurement results exhibit that the clamp is robust against false triggering and the latch-up. The proposed clamp passes both +3.5 and -4.5 kV HBM stresses and passes +700 and -450 V CDM stresses.

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.
