Vertical-TFT is a promising structure to realize ultra-high resolution displays. Especially, low-resistive Al-based source/drain is necessary to reduce RC delay. Since vertical-TFT is bottom-contact structure, source/drain is oxidized during InOx semiconductor deposition. Here, we present the quantitative analysis result of metal/active contact properties in top-gate bottom-contact structured TFT, mimicking vertical-TFT.
