Node Warfare?


By Mark LaPedus & Ed Sperling GlobalFoundries uncorked a 12nm finFET process, which the company said will provide a 15% increase in density and more than 10% improvement in performance over the foundry's existing 14nm process. This is GlobalFoundries' second 12nm process. It announced a 12nm FD-SOI process called 12FDX last September, although it first mentioned a 12nm process back in J... » read more

Frenzy At 10/7nm


The number of chipmakers rushing to 10/7nm is rising, despite a slowdown in Moore's Law scaling and the increased difficulty and cost of developing chips at the most advanced nodes. How long this trend continues remains to be seen. It's likely that 7/5nm will require new manufacturing equipment, tools, materials and transistor structures. Beyond that, there is no industry-accepted roadmap, m... » read more

Tech Talk: 7nm Thermal Effects


ANSYS' Karthik Srinivasan talks about the effect of heat on reliability at advanced process nodes, including self-heating, circuit aging, and how that will affect automotive electronics. https://youtu.be/SS6iAXp0Kn8   Related Tech Talk: 7nm Power Dealing with thermal effects, electromigration and other issues at the most advanced nodes. » read more

Machine Learning In The Fab


Machine learning is exploding, especially where there are massive amounts of data to contend with and lots of potential interactions. This leads to two obvious insertion points in the semiconductor field. One is on the design side, where just getting an advanced design to function is an enormous challenge. That challenge increases as the need for reliability in some market increases. It's d... » read more

What’s After FinFETs?


Chipmakers are readying their next-generation technologies based on 10nm and/or 7nm finFETs, but it's still not clear how long the finFET will last, how long the 10nm and 7nm nodes for high-end devices will be extended, and what comes next. The industry faces a multitude of uncertainties and challenges at 5nm, 3nm and beyond. Even today, traditional chip scaling continues to slow as process ... » read more

Can A Supply Chain Be Too Efficient?


The semiconductor industry is a model of efficiency—literally. When other industries look at adding smart manufacturing into their operations, they often look to chip manufacturing as a shining example. After decades of business gyrations, semiconductor companies have figured out how to instill efficiency into every aspect of making chips. This is evident in device scaling. At 90nm, the co... » read more

Is 7nm The Last Major Node?


A growing number of design and manufacturing issues are prompting questions about what scaling will really look like beyond 10/7nm, how many companies will be involved, and which markets they will address. At the very least, node migrations will go horizontally before proceeding numerically. There are expected to be more significant improvements at 7nm than at any previous node, so rather th... » read more
