Summary:Electrostatic discharge (ESD) failure modes in advanced CMOS
processes have been electrically and physically characterized, and an
analysis has been made of the mechanisms of each of the main failure
modes. The physical failure modes have been related to the electrical
degradation and, therefore, the electrical signatures of the damage
mechanisms have been obtained. The distribution of the electrical
characteristics after ESD stress, for a given process or design
variation, can then be used to identify freak failures and process
defects. Investigations of the influence of processing steps such as
silicides, lightly doped drains (LDDs), thin gate oxides, bird's-beak
suppression, and barrier metallization on the electrical damage
characteristics and the failure modes are presented and analyzed
