This should of course be 300nm not 300mm referring to nominal feature size on the silicon. Edit: I'm wrong 300mm refers to the wafer size and the later reference in the article to 200nm should be 200mm.

300 mm is correct. It refers to the wafer size.

Are we sure that it's not 300mm, referring to size of the wafer? Although I'm not sure automotive silicon normally takes place in 300mm fabs...

No, 300mm is correct and refers to physical size of whole silicon wafer[1]. 300mm (commonly known as 12") is currently the biggest class of silicon wafers.

Naka factory was producing 300mm wafers using 28nm process [2].

Are you sure? It’s a 300mm wafer fab.

Here’s another article that outlines their current fab wafer size.

They use 200nm later in the article, but wikipedia[0] says that 300mm is a standard wafer size, and fabs are classified by the diameter of wafer, so you might be right. I assumed it was the feature size before, too.

It's confusing because they refer to "200nm" in the same article.
