We in Semiwiki are writing about FD-SOI since 2012, describing all the benefits offered by the technology in term of power consumption, price per performance compared with FinFET, etc. Let me assess again that I am fully convinced that FD-SOI is a very smart and efficient way to escape from the Moore's law paradox: the transistor cost is increasing for (FinFET) technology node below 20 nm, and that I expect FD-SOI to see market adoption.

But I think that some people are confused when dealing with FD-SOI. When you see some picture like this "SOI Roadmap" (from VLSIResearch), it seems that the picture designer has just made a copy of the Bulk Roadmap and pasted it with 2 years shift. Even if 28 and 22 nm FD-SOI become successful technologies –that I hope- it will take some time for the foundries supporting these nodes to generate enough ROI before investing in a way as described on this graphic.
