What’s After CMOS?

Chipmakers continue to scale the CMOS transistor to finer geometries, but the question is for how much longer. The current thinking is that the CMOS transistor could scale at least to the 3nm node in the 2021 timeframe. And then, CMOS could run out of gas, prompting the need for a new switch technology. So what’s after the CMOS-based transistor? Carbon nanotubes and graphene get the most a... » read more

What Comes After FinFETs?

By Mark LaPedus The semiconductor industry is currently making a major transition from conventional planar transistors to finFETs starting at 22nm. The question is what’s next? In the lab, IBM, Intel and others have demonstrated the ability to scale finFETs down to 5nm or so. If or when finFETs runs out of steam, there are no less than 18 different next-generation candidates that could o... » read more
