At 130nm, the introduction of copper interconnects, 300mm wafers and low-k dielectrics left the entire supply chain breathless. There had never been as many changes at a single process node in the history of semiconductors.
At 28nm, the number of changes will pale compared to what’s necessary at 20nm, and that will pale to what’s required at 14nm. But unlike 130nm, when most of those cha...
