  • Patent number: 8395149
    Abstract: A semiconductor device structure on a substrate and a manufacture method thereof is provided. The semiconductor device structure includes an oxide semiconductor transistor and a passivation layer containing free hydrogen. The semiconductor device structure is formed by following steps. A gate electrode is formed on the substrate. A gate dielectric layer covers the gate electrode. A source electrode is formed on the gate dielectric layer. A drain electrode is formed on the gate dielectric layer and separated from the source electrode and thereby forming a channel distance. An oxide semiconductor layer is formed on the gate dielectric layer, the source electrode and the drain electrode and between the source electrode and the drain electrode. The oxide semiconductor layer is further electrically connected with the source electrode and the drain electrode. A passivation layer covers the oxide semiconductor layer, the source electrode and the drain electrode.
