  • Abstract
    Threshold voltage (VTH) variability of 10G (10 billion) transistors is measured using a special device-matrix-array test-element-group (DMA TEG) exclusively for ultra-fast VTH measurements. It is found that VTH variability in nFETs almost follows the normal distribution up to ±6σ, while pFETs have a clear “tail” in low VTH region. The origin of the non-normal distribution is analyzed by measuring transistors fabricated in two different fabs and by 3D device simulation.
