Abstract :
We have successfully developed the new design of MOSFET array structure with high accuracy measurement both for Ion excluding IR drop and Ioff without contamination. We propose measurement algorithm “feedback looped biasing” with kelvin probe structure and canceling method for leakage contamination due to array peripherals. This test structure is implemented in scribe line for 28nm technology and beyond. And we get layout dependency of MOSFET characteristics and mismatch characteristics.
