ESD characterization of gate-all-around (GAA) Si nanowire devices

In CMOS scaling roadmap, gate-all-around (GAA) nanowire (NW) is a promising candidate in sub-10nm nodes. However, newly introduced process options in GAA NW technologies can result in significant impacts on intrinsic ESD performance. In this work, ESD protection devices in GAA NW architecture are studied and the corresponding 3D TCAD simulations bring an in-depth understanding.
