What is the fine-grained topic of the following text: Vice president of R&D at TSMC Cliff Hou told EE Times that the FinFET process will have the same leakage power characteristics as the 20-nm process on which it is based, but it will boost performance boost by up to 35 percent and reduce total power consumption by around 35 percent compared to 20 nm. Only return the topic.
