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.
History
Technology demos
In July 2015, IBM announced that they had built the first functional transistors with 7 nm technology, using a silicon-germanium process.[1][2]
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.[3] A possible replacement material for silicon would be indium gallium arsenide (InGaAs) or graphene.[4]
In April 2016, TSMC announced that 7 nm trial production would begin in the first half of 2017.[5] In March 2017, TSMC announced 7 nm risk production starting by June 2018.[6]
In September 2016, GlobalFoundries announced trial production in the second half of 2017 and risk production in early 2018, with test chips already running.[7]
In February 2017, Intel announced Fab 42 in Arizona will produce microprocessors using 7 nm manufacturing process.[8]
process nodes
Transistor gate pitch is also referred to as contacted poly pitch (CPP) and interconnect pitch is also referred to as minimum metal pitch (MMP).[9][10][11] The ITRS roadmap initially suggested a 7nm node with a poly pitch of 42nm with a metal pitch of 24 nm[10]. Samsung proposed a 7nm process with a poly pitch of 44 nm with a metal pitch of 36 nm. Likewise, TSMC 7 nm is proposed at 54 nm by 40 nm respectively[11].
