Among three chip-level electrostatic discharge (ESD) test standards, which were human-body model (HBM), machine model (MM), and charged-device model (CDM), the CDM ESD events became critical due to the larger and faster discharging currents. Besides input/output (I/O) circuits which were connected to I/O pads, core circuits also suffered from CDM ESD events(More)
Due to the thinner gate oxide in the nanoscale CMOS technology and the larger chip size in the system-on-chip (SoC) IC products, the charged-device-model (CDM) electrostatic discharge (ESD) has become the major ESD events to cause failures during IC manufacturing procedures. The effective ESD protection design against CDM ESD stresses should be implemented(More)
