Abstract :
Different electrostatic discharge (ESD) devices in a 0.35-μm silicon germanium (SiGe) RF BiCMOS process are characterized in detail by a transmission line pulse (TLP) generator and ESD simulator for on-chip ESD protection design. The test structures of diodes with different p-n junctions and the silicon-germanium heterojunction bipolar transistors (HBTs) with different layout parameters have been fabricated to investigate their ESD robustness. The human-body-model (HBM) ESD robustness of SiGe HBTs with the optional low-voltage (LV), high-voltage (HV), and high-speed (HS) implantations has been measured and compared in the experimental test chips.
