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.
- philipkglass 6y ago300 mm is correct. It refers to the wafer size. https://en.wikipedia.org/wiki/Wafer_(electronics)#Standard_wafer_sizes https://en.wikipedia.org/wiki/Wafer_(electronics)#Standard_w...
- rossdavidh 6y agoAre 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...
- andrewflnr 6y agoThey 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. [0] https://en.wikipedia.org/wiki/Wafer_(electronics) https://en.wikipedia.org/wiki/Wafer_(electronics)
- terramex 6y agoNo, 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].

- skunkworker 6y agoAre you sure? It’s a 300mm wafer fab. Here’s another article that outlines their current fab wafer size. https://www.eetimes.com/renesas-to-expand-300-mm-fab-in-90-65-nm-push/ https://www.eetimes.com/renesas-to-expand-300-mm-fab-in-90-6...
- centimeter 6y agoIt's confusing because they refer to "200nm" in the same article.
