Abstract :
We designed an addressable transistors array to analyse local variability at the wafer scale. On FDSOI substrates, we measure no impact of the silicon thickness variations on short channel transistors, and demonstrate that the impact on large area transistors is no more visible when the Tsi is well controlled.
