A graphene NEMS switch to protect against electrostatic discharging

Tue, 12/04/2018 - 13:08
One of the most pervasive reliability problems facing the computer chip industry is ESD (electrostatic discharging) failure caused by the rapid, spontaneous transfer of electrostatic charge induced by a high electrostatic field. A novel above-IC graphene based nanoelectromechanical system (NEMS) switch structure for on-chip ESD protection utilizes the unique properties of graphene. This switch is a two-terminal device with a vacuum gap between a conducting substrate at the bottom and a suspended graphene membrane on top serving as the discharging path.
