If Intel had problems going 10nm, how did TSMC go 7nm then? Something isn't right? Or some companie ...

most rumours are suspecting that intel introduced cobalt for interconnect layer hoping for lower resistance, which tsmc's 7nm remains using copper. as they faced the yield problem with the new material they cannot roll back to copper without a complete redesign
