A few short years ago 7nm was a holy grail, something to be sought for but unlikely to be successful.  The richest knight in the kingdom is still seeking their goal, while the squires have already got one.  AMD is doing well with their process but it is Sir Samsung whom has met with the most success.  Their trusty EUV proved up to the task and they are no longer seeking a 7nm process and have moved onto sharing the benefits of their quest with the world.  The new chips will be Low Power Plus, and find their way into smartphones, and cell providers, IoT devices and many other applications in the small endian market.  The Inquirer posted a look at how they got there, as well as some definitions if this is all Gallic to you. 

"Normally argon fluoride immersion tech is used for chip lithography. But Samsung is touting the advantages of EUV in cutting down the number of masks needed to allow for the stencilling of transistors on silicon in a certain pattern, and thus cuts down on the time and costs of producing chips."
