Well I'd have to say that since you don't know what the breakthrough is, nor do you really appear to understand the technical issues involved (other than quoting words from the article)... I'm not sure you are really saying anything. Much like my post
Breakthrough's in science can be very simple things that move projects forward significantly. A breakthrough doesn't require a nuke going off, or a plane breaking a new mach record.... it could be as simple as what they state as to resolve an issue that was holding up the project for months.
Of course you might think what they did is "simple" and not breakthrough worthy, but that just demonstrates a lack of understanding for the difficulty in what they are working with.
You do understand we are talking about nano sized circuits here right?
