Abstract
This work proposes a Bulk+ planar fully depleted “folded” technology as an innovative cost worthy solution for upcoming low power nodes. We report a detailed fabrication method, combining advanced selective epitaxy faceting and SON (Silicon-On-Nothing) process, to provide thin film/thin BOX devices with improved transistor gain β for a given designed footprint W design . We compare the fabrication between 〈110〉 channel, i.e. non-rotated wafer, and 〈100〉 channel, i.e. 45°-rotated wafer, for the same (100) surface orientation.
