A roadmap from a slide by ASML presented at the IEDM conference recently shared on Anandtech shows Intel Roadmap for the next ten years with 7nm manufacturing process expected in 2021, 5nm in 2023, 3nm in 2025, 2nm in 2027, and 1.4nm in 2029.
Intel did however contact Anandtech to explain the slide from ASML is a modified version of the Intel slide shown below that does not show actual process nodes, only the dates. I suppose Intel does not want to make any commitments seeing how their 10nm technology suffered delays after delays, and in any case the actual dimensions of the process may vary by that time frame depending on difficulties or new discoveries made.
Both slides mention +, ++, and backport opportunities for all new processes. + and ++ are just iterative improvements for the current process, while back- porting is the option to port a process developed on the latest node to the previous ++ process node (e.g. a 5nm processor, may end up being a 7nm++ processor) possibly for cost-reasons or delays in the new process. The 10nm will apparently have 3 iterative improvements since the slide shows both 10nm++ and 10nm+++ are planned.
The 2nm and 1.4nm process technologies are still at the research stage, so we’ll have to see whether researchers can solve challenges brought about by such tiny process nodes.
