Patent number: 12132042Abstract: The ability of a grounded gate NMOS (ggNMOS) device to withstand and protect against human body model (HBM) electrostatic discharge (ESD) events is greatly increased by resistance balancing straps. The resistance balancing straps are areas of high resistance formed in the substrate between an active area that includes a MOSFET of the ggNMOS device and a bulk ring that surrounds the active area. A Vss rail is coupled to the substrate beneath the MOSFET through the bulk ring. The substrate beneath the MOSFET provides base regions for parasitic transistors that switch on for the ggNMOS device to operate. The straps inhibit low resistance pathways between the base regions and the bulk ring and prevent a large portion of the ggNMOS device from being switched off while a remaining portion of the ggNMOS device remains switched on. The strap may be divided into segments inserted at strategic locations.Type: GrantFiled: July 25, 2022Date of Patent: October 29, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Hsiao-Ching Huang, Sheng-Fu Hsu, Hao-Hua Hsu, Pin-Chen Chen, Lin-Yu Huang, Yu-Chang Jong
