Globalfoundries, TSMC, AMD and even Samsung may be sued for false advertising as their nm claimed sizes are completely false as a 14nm is closer to 20nm but they still name it 14nm and the recent claims by AMD of skipping 10nm and going to 7nm is false - it's more like 14nm. This is huge news and everybody should be made aware:
Understanding how foundries name their process nodes: Intel’s 10nm versus TSMC 10nm and beyond
"The answer lies in the fact that Intel’s naming standards and TSMC’s naming standards are drastically different. Intel’s processes use the same backbone as the advertised node (a 14nm process will use a 14nm backbone) while as all pure play foundries use a mixture of process technologies. TSMC’s 16nm FinFET tech for example uses a 20nm backbone (BEOL). So it is almost a certainty that they will be using a 14nm BEOL for their ’10nm finfet’ node.
"Let me explain a bit further, the process names that foundries use have now become more or less marketing material and not accurate physical descriptions of the node (except maybe in the case of Intel). Simply marketing a node as 7nm FinFET or 10nm FinFET does not make it a true 7nm or 10nm node respectively. I think the most relevant benchmark in this case (in my attempt to explain the point) is that of the Transistor Gate Pitch. This is the measure which is usually a very good indicator of the “true” node that a foundry might be using."

So when Globalfoundries, TSMC, AMD and Samsung claim they have a 14nm it's more like 20nm and their 10nm is more like 14nm and their 7nm it's more like 10nm. Sorry. I wish it were true too but, it's not their 7nm is more like 10nm.
