Taiwanese foundry UMC revealed it will aggressively develop 14nm process technology that supports FinFET 3D transistors. UMC CEO Shih-Wei Sun said deploying FinFET technology is now a must for chip makers in order to keep Moore's Law alive and kicking. Sun also revealed that 28nm would account for about 5 percent of UMC's revenue by the end of the year, and added that small volume production of 20nm will start sometime in the second half of 2013.

Moore's Law sketches out the concept of shrinking semiconductor device dimensions, but the shrinking of technology nodes will have to overcome some challenges, particularly cost-related barriers. The transition to 20nm process technology shows that the pace of cost reduction for transistor production has been slowing, Sun pointed out.
Transition to a newer process should enable a 25% improvement in performance, and the manufacturing cost per transistor should also fall at the same rate in order to be cost effective, Sun said. The current shift to 20nm process from 28nm has encountered problems associated with rising equipment costs for double patterning techniques, and performance is only able to see a 15% improvement, Sun indicated.
"Based on our IBM FinFET licensing, UMC has decided to aggressively develop 14nm FinFET technology on 20nm metal. 14nm FinFET will deliver the most optimal low-power and high-performance solution to offset the cost impact from using double patterning lithography," Sun said.
