  • Publication number: 20240030215
    Abstract: 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.

  • Publication number: 20230420392
    Abstract: Some implementations described herein provide techniques and apparatuses for a stacked-die structure including a first integrated circuit device over a second integrated circuit device, where an operating voltage of the first integrated circuit device is different relative to an operating voltage of the second integrated circuit device. The first integrated circuit device includes a first portion of a seal ring structure of the stacked-die structure. The first portion includes an interconnect structure that connects a backside redistribution layer of the first integrated circuit device with first metal layers of the first integrated circuit device. The seal ring structure including the interconnect structure eliminates the use of diodes and electrically isolates well structures of the first integrated circuit device to reduce leakage paths relative to a stacked-die structure having a seal ring structure including a diode within the stacked-die structure.

  • Publication number: 20220367614
    Abstract: An avalanche-protected field effect transistor includes, within a semiconductor substrate, a body semiconductor layer and a doped body contact region having a doping of a first conductivity type, and a source region a drain region having a doping of a second conductivity type. A buried first-conductivity-type well may be located within the semiconductor substrate. The buried first-conductivity-type well underlies, and has an areal overlap in a plan view with, the drain region, and is vertically spaced apart from the drain region, and has a higher atomic concentration of dopants of the first conductivity type than the body semiconductor layer. The configuration of the field effect transistor induces more than 90% of impact ionization electrical charges during avalanche breakdown to flow from the source region, to pass through the buried first-conductivity-type well, and to impinge on a bottom surface of the drain region.
