If you haven't watched it, there was a fantastic 2009 talk (given during HOPE09) on what goes into fabrication called "Indistinguishable From Magic: Manufacturing Modern Computer Chips" [1]. Keeping in mind things have advanced even farther over the subsequent decade, even at that point it was mind blowing what goes into the hardware at the core of what we all do. The level of purity and consistency needed for a lot of basic inputs is measured in atoms, really digging into the details it's amazing some of this works at all let alone with high yields. Helps give some context of how an incident like this can happen and how easily the cost could rapidly rise to eye watering levels.
I think Andor has posted on HN since too with some other high level talk, though not further updates per se since unsurprisingly details around fabrications are very heavily guarded trade secrets. I still rewatch it every year or two, it remains a real source of wonder to me what we've pulled off there.
