Good, informative read: In SemiMD, FD-SOI Targets Mobile Applications by Giorgio Cesana of
ST and Carlos Mazure of Soitec. The article explains why FD-SOI is perfectly suited for mobile IC
applications where power consumption has to be very low to maximize battery lifetime. The authors
compare the technology to planar bulk and FinFETs, touching on body-biasing, substrates, design,
and circuit results/performance.
