Both processes will use what's known as high-k metal gate technology. High-k can be built either through the use of a "gate-first" or a "gate-last" approach. Intel—the only company to date that's shipped high-performance / high volume products using high-k—favors the gate-last approach. GlobalFoundries, IBM, and Samsung are championing gate-first technology. Proponents of gate-first technology argue that it allows for less-restrictive designs, smaller dies, and is easier to build. It's also cheaper. GF expects to save ~$75 million over four years by opting for gate-first rather than gate-last. Gate-last proponents (Intel, TSMC) claim that gate-first technology isn't a long-term solution and can't deliver all the benefits of the gate-last approach."
