Web1 dec. 2009 · For UTB-SOI MOSFETs, a mobility extraction test structure has been proposed that includes additional contacts to the inversion layer [9].These allow four-point probe measurements of the intrinsic voltage drop across the channel (compare Fig. 1 a) and thus eliminate access series resistance. While this mobility test structure has been … Web13 feb. 2015 · An intrinsic short channel mobility extraction method is proposed by measuring two short-channel devices with different channel lengths and the same source/drain and contact geometry. The constant and dynamic components of external resistance are separated. Short-channel mobility degradation is observed and its origin … number of prime factors formula
