In semiconductor manufacturing, the International Technology Roadmap for Semiconductors defines the 7 nanometer (7 nm) node as the technology node following the 10 nm node.
Single transistor 7 nm scale devices were first produced in the early 2000s – as of 2017 commercial production of 7 nm chips is at a development stage.
In 2012, IBM produced a sub-10 nm carbon nanotube transistor that outperformed silicon on speed and power. "The superior low-voltage performance of the sub-10 nm CNT transistor proves the viability of nanotubes for consideration in future aggressively scaled transistor technologies," according to the abstract of the paper in Nano Letters.
Expected commercialisation and technologies
Although Intel has not yet divulged any certain plans to manufacturers or retailers, it has already stated that it would no longer use silicon at this node. A possible replacement material for silicon would be indium gallium arsenide (InGaAs) or graphene.
