Patent
Uniform current distribution SCR device for high voltage ESD protection
TL;DR: In this article, a p+ diffusion is added to the source of one of the NMOS transistors to guarantee that the resistance seen by both SCRs is identical, which improves the high voltage characteristics of the ESD device.
Patent
Combined NMOS and SCR ESD protection device
Jian-Hsing Lee,Kuo-Chio Liu +1 more
TL;DR: In this paper, a low triggering voltage was achieved by having the second parasitic npn transistor of the SCR in parallel with the NMOS (DENMOS) transistor by sharing the n-well (collector/drain), p-substrate (base/channel region), and an adjacent n+ diffusion (emitter/source) in the psubstrate.

Patent
High voltage ESD protection device with very low snapback voltage by adding as a p+ diffusion and n-well to the NMOS drain
TL;DR: In this paper, the authors described a device layout for an ESD device for protecting NMOS high voltage transistors where the SCR protection device and the two NMOS transistors are integrated.
