Without employing an unconventional thin‐film transistor (TFT) with excessively wide effective channel width and offset source/drain electrodes, an improved methodology and circuit are applied to measuring the off‐state current ( I off ) of elevated‐metal metal‐oxide (EMMO) TFTs built on indium‐gallium‐zinc oxide, with or without fluorination. I off of around mid‐10 −18 A/μm has been obtained, with the value slightly lower for an EMMO TFT with a fluorinated channel.
