A test structure to analyze asymmetry and orientation dependence of MOSFETs is presented. n-MOSFETs with 8 different channel orientation and three kinds of process conditions were measured and symmetry characteristics of I_Dsat and I_Bmax with respect to the interchange of source and drain was examined. Although both I_Dsat and I_Bmax have similar channel orientation dependence, I_Bmax in interchanged S/D measurements shows asymmetrical characteristics, which can be applied to a sensitive method for device asymmetry detection.
