ESD basic: Silicon Control Rectifier (SCR)

SCR intro: Silicon-controlled rectifiers (SCRs) are interesting devices that can be used for on-chip ESD protection, if (and only if) they are properly designed and biased. SCRs are used for high-speed/RF or low-capacitance, small area/high-performance ESD solutions in all CMOS technologies, including SOI and FinFET (down to 3nm today). SCR operation: Figure 1 introduces the…

ggNMOS (grounded-gated NMOS)

ggNMOS intro: For decades, a traditional workhorse device for ESD protection for standard applications in CMOS technology has been the grounded-gate NMOS device (ggNMOS). Nevertheless, we have been explaining the operation of this device countless times, including as recently as 3 weeks ago. So, it is time for a short blog article. The schematic of…

Let’s talk about 2023

Sofics’ CEO outlook for 2023… 2023 will be a year of opportunity to invest in our readiness to grow and flourish in 2024. Whatever your semiconductor business, your key assets: team, skills, technology, processes, and reputation, should not go to waste.

Optimized Local I/O ESD Protection for SerDes In Advanced SOI, BiCMOS and FinFET Technology

Sofics’ 2021 IEDS publication. Semiconductor companies are developing ever faster interfaces to satisfy the need for higher data throughputs. However, the parasitic capacitance of the traditional ESD solutions limits the signal frequency. This paper demonstrates low-cap Analog I/Os for high speed SerDes (28Gbps to 112Gbps) circuits created in advanced BiCMOS, SOI and FinFET nodes.
