In this paper
We research LOD and WPE effects of self-developed 40nm process PDK.The parameter SA of LOD effect and the parameter left of WPE effect influence the characteristics of CMOS device
especially the saturation current I and the threshold voltage V. With the decrease of SA
I of NMOS decreases by 4.25% and V increases by 2.79%.The relationship between electrical parameters and SA of PMOS is consistent with that of NMOS
but the trend is stronger than NMOS
I decreases by 8.32% and V increases by 6.78%. The physical mechanism of LOD effect is explained.With the decrease of left
the I of NMOS decreases by 9.03% and V increases by 12.5%.The relationship between the electrical parameters of PMOS and left is weaker than that of NMOS
I decreases by 8.50%
and V increases by 4.61%.The cause that the electrical parameters change under WPE effect is proposed. In the nanometer process PDK
the accurate application of LOD and WPE effects can better simulate device performance
and improve the precision of circuit.
