High resolution two-dimensional carrier profiling on sub-100nm silicon nano-devices using scanning spreading resistance microscopy
2004
This work presents the recent progress in scanning spreading resistance microscopy( SSRM) capabilities highlighting enhanced spatial resolution (<5 nm) and excellent concentration sensitivity (<20%). The latter is demonstrated through the analysis of three carrier profiling applications i.e. the calibration of process simulations for a 90 nm n-MOS technology, the determination of the impact of nitridation on the lateral diffusion in a 40 nm n-MOS technology and the study of activation problems in SPER-anneals of shallow implants.
