Firm predicts it will cost $28 billion to build a 2nm fab and $30,000 per wafer, a 50 percent increase in chipmaking costs as complexity rises::As wafer fab tools are getting more expensive, so do fabs and, ultimately, chips. A new report claims that
This was my understanding as well: That beyond ~7nm the reliability begins to lose value because the diameter of an electron ‘orbit’ or whatever becomes a factor.
Admittedly I’m not an expert. But my understanding was that to break this limitation and keep Moore’s law were kinda leaning into quantum computation to eventually fill the incoming void.
