Intel produced this short video on their new 22 nm finFET technology. The video is very cool and well done, but wish it included some SEM images of chip as well. Or better yet, if the speaker walked off screen at the end across a 3D landscape of 3D FETs. This would be my version of the Ark/warehouse storage scene at the end of the first Indiana Jones movie. Anyway, the 2D planer channel has been transformed into a 3D fin that allows the gate to wrap around three sides of the channel. This provides better on-off control and lower leakage.
