The 5 nanometer (5 nm or 50 Å) lithography process is a technology node semiconductor manufacturing process following the 7 nm process node. Commercial integrated circuit manufacturing using 5 nm process is set to begin sometimes around 2020.
The term "5 nm" is simply a commercial name for a generation of a certain size and its technology, and does not represent any geometry of the transistor.

Intel
In May of 2017, Intel's Technology and Manufacturing Group Director, Mark Bohr, confirmed that Intel was already started researching their 5 nm node as their 7nm was already in development phase.
TSMC
The TSMC 5nm node uses a FinFET transistor like their 7nm process, but it makes more extensive use of EUVL. This provides a transistor density improvement of 30%-80%, and a reduction in transistor variability. The process will provide a 15% speed improvement or a 30% reduction in power compared to their standard 7nm process.
Common Platform Alliance Paper
In a joint paper by the Common Platform (IBM, GlobalFoundries, Samsung) a 5nm node was proposed at the 2017 VLSI Symposium. The paper presents a new horizontally stacked sheet gate-all-around (GAA) FET with good properties which can be a good candidate for the replacement of FinFET at the 5nm node. The paper reports transistors with an aggressive Lg of 12 nm and a contacted poly pitch of 48 nm.
