You better hope AMD is not still working on finfets


BTL: So, if I'm reading the reference correctly, the main issue with finfets, seems to be the body thickness, and the Fab difficulties, but then the article goes on to suggest a solution....


As the transistors scale to Lg=20nm, the body
thickness will need to be of the order of 6-7nm. Apart from
the fabrication issues for such thin bodies discussed
above, the increase in series resistance arising from ultrathin junctions will limit transistor drive currents........


The solution to the drive current issue (from external
parasitic resistance) is to use raised source/drain, which
increases the effective thickness of the junctions and
hence the junction conductance.....



So, am I missing something, or could not AMD's PE's have figured out that raised S/D solution too?
