“We are developing 22nm FD-SOI process technology right now.” The plan is to qualify the process by early 2016 and start volume production by the end of 2016.

Asked about what the company’s 22nm FD-SOI process entails, Teepe explained, “We are using STMicroelectronics’ 14nm FD-SOI in our frontend, while using 28nm FD-SOI in the backend.”

So 14nm frontend and 28nm backend, so (14+28)/2 = 21, so they called it 22nm for marketing reasons
