Will CFETs Help The Industry Go Vertical?
By Katherine Derbyshire - 15 Jun, 2023 - Comments: 0

Device scaling is getting much harder at each new process node. Even defining what it means is becoming a challenge. In the past, gate length and metal pitch went down and device density went up. Today, this is much harder for several reasons: • Short channel effects limit gate-length scaling; • Parasitic effects limit device density, and • Metal resistance limits metal pitch. So r... » read more

New Materials Open Door To New Devices
By Katherine Derbyshire - 21 Jul, 2022 - Comments: 0

Integrating 2D materials into conventional semiconductor manufacturing processes may be one of the more radical changes in the chip industry’s history. While there is pain and suffering associated with the introduction of any new materials in semiconductor manufacturing, transition metal dichalcogenides (TMDs) support a variety of new device concepts, including BEOL transistors and single-... » read more

Foundries Prepare For Battle At 22nm
By Mark LaPedus - 19 Nov, 2018 - Comments: 0

After introducing new 22nm processes over the last year or two, foundries are gearing up the technology for production—and preparing for a showdown. GlobalFoundries, Intel, TSMC and UMC are developing and/or expanding their efforts at 22nm amid signs this node could generate substantial business for applications like automotive, IoT and wireless. But foundry customers face some tough choic... » read more

Understanding The Effect Of Variability In Bulk FinFET Device Performance
By Coventor - 30 May, 2018 - Comments: 0

2-D MOSFETs have proven difficult to scale down to 20nm and beyond. In their place, 3D FinFET transistors have emerged as novel devices that can scale down to lower node sizes. 10nm process finFETs are for SoC product mass production, and research is progressing towards a 7nm process finFET. FinFET transistors provide lower dynamic power consumption (due to flatter I-V curves), improved control... » read more

Bulk CMOS Vs. FD-SOI
By Mark LaPedus - 19 May, 2016 - Comments: 2

The leading edge of the chip market increasingly is divided over whether to move to finFETs or whether to stay at 28nm using different materials and potentially even advanced packaging. Decisions about which approach to take frequently boil down to performance, power, form factor, cost, and the maturity of the individual technologies. All of those can vary by market, by vendor and by process... » read more

FinFET Rollout Slower Than Expected
By Mark LaPedus - 16 Apr, 2015 - Comments: 1

The foundry business is heating up as some new and large players are entering the 16nm/14nm [getkc id="185" kc_name="finFET"] market. But foundry customers are taking longer than expected to migrate to finFETs amid some technical and cost issues. On the foundry front, [getentity id="22846" comment="Intel"] has been the sole player in finFETs for some time. But now, [getentity id="22865" ... » read more
