Intel plans to build 1.4nm nodes by 2029
Table of contents:
A roadmap of Intel's process technology has emerged (reported by WikiChip) that sees Intel introducing a new process every two years for the next decade, resulting in the 1.4nm node in 2029. There will also be two additional optimizations within from the same node, with a 10nm +++ in 2021.
Intel plans to build 1.4nm nodes by 2029
The roadmap was shown in an ASML presentation at the ongoing IEDM 2019 conference and dates back to a September Intel presentation. It shows 10nm in 2019, 7nm in 2021 and 5nm in 2023, respectively in development and in definition. In October, Intel announced its intention to return to a cadence of two to two and a half years and declared its confidence in the 5nm node.
The roadmap reveals that Intel has 3nm and 2nm on the way and the 1.4nm node is under investigation at the moment. It is the first time that Intel has revealed that it is working on those nodes. The time span between all nodes is approximately two years, placing 3nm in 2025. However, since the 7nm launch is scheduled for the fourth quarter of 2021, any small delay in the next decade would let 3nm come later. and hence would also drag 1.4nm by 2030 or beyond.
The roadmap does not reveal any details about the changes they will introduce at the technological level, apart from saying that each node would be the optimal cost performance route and would introduce new features. For 7nm, that means inserting EUV. By 5nm, Intel is expected to move from current FinFETs to nanowire FinFETs stacked on later nodes. Intel is also likely to aim to use the next generation of high-NA 5-nm EUV lithography: Intel's director of lithography recently made “a call to action to keep a high-NA-content EUV running” for its 2023 calendar, according to SemiEngineering .

Lastly, Intel announced at its investor meeting this year that the company will continue the practice that started at 14nm of introducing process optimizations within the node (called '+' revision).
So far, no manufacturer has spoken openly about nodes smaller than 3 nm in development, so this information is interesting. We will keep you informed.
