As I wrote in May, ST-E reckons that w/FD-SOI's power savings, they can add a full extra day for smartphone users (see http://www.advancedsubstratenews.com/2012/05/novathor-smartphone-chip-on-28nm-fd-soi-st-ericsson-blogger-tells-all-pc-mag-sees-light/), which is huge. And IBS says that even counting the cost of the wafer, per-die FD-SOI comes in at about *half* the cost of bulk (planar and/or FinFET) at 20nm (which ST has in very-fast-follow), because it saves process steps -- see http://www.advancedsubstratenews.com/2012/11/ibs-study-concludes-fd-soi-most-cost-effective-technology-choice-at-28nm-and-20nm/

I believe that ST-Erikson are willing to pay extra for their wafers in order to reap the 40 percent savings in battery power, which mitigates the risk. The other guys are just validating that they can get the higher performance, and by the time they get to volume production, the price may have gone down due to high demand. Of course, bulk silicon will always be cheaper for the raw wafers.

Bold move from ST and STE. If you don't take the risk you cannot win.

SOITEC quotes $500 per FD-SOI wafer when shipping in volume. Since ST by itself does not make up too much volume, I wonder how costly this is going to be...

Timing almost like outgoing CTO's last decision.
