Abstract :
For the first time we demonstrate the CMOS integration of undoped fully-depleted Ultra Thin Body and BOX devices (UTB2) with (110)/(100) substrate crystal orientation for pFET and nFET respectively. For this, we used an original 3D-folded Bulk+/Silicon-On-Nothing (SON) process on DSB substrate. Resulting multi-surface orientations devices are studied.
