The 2010 decade was momentous for semiconductors in its huge structural shifts. It was a battle over two ideologies: Greater productivity to lower cost with 450mm wafers versus new technologies to drive new markets via the introduction of Materials Enabled Scaling, Multi-patterning, and EUV. The industry could not afford both and in the end chose innovation. It was also the decade it which partnering for profit became fully accepted as well as the end of mega-mergers in the equipment industry. Dan Hutcheson and Andrea Lati have a conversation about why it happened and what it could portend for the coming decade.
