Popis: A new technique for a separate extraction of the current-path-dependent resistance (RSD0) from the contact-dependent source and drain resistances (RSe and RDe) is reported for a single MOSFET. We also report a technique for a separation of VGS-dependent source and drain resistance (RSDi) from the VGS- and Leff-dependent channel resistance (Rch) with multiple MOSFETs. We confirm the proposed techniques applied to n-channel MOSFETs with various W/L combinations and obtain RSe = 10.5 - 12.4 Ω , RDe ≅ 12.7 Ω, and RSD0 = 4.7 Ω for W = 10 μm. VGS-dependent but L-independent RSDi is extracted to be 2.8 - 4.2 Ω.
