Intel's 10nm strategy was basically to do everything they could to advance their fabrication process without having to use EUV. Some of those changes turned out to be bigger risks than EUV. TSMC was a bit less aggressive with their last non-EUV nodes, but it actually worked and now they have EUV in mass production (though few if any end-user products have switched over to the EUV process at this point).

Thanks for the correction.
