Double-well field effect diode vs. SCR behavior under CDM stress in 45nm SOI technology

In this paper, we present a comparison of the turn-on voltage between SOI-SCR, and the novel DWFED structure. We show that DWFED can achieve faster turn-on, protecting the low voltage devices more effectively. Using the pulse waveforms, we justify the use of a gate trigger circuit for the DWFED to reduce the transient spikes under faster CDM pulses.
