  • Patent number: 11935935
    Abstract: A thin film transistor includes a gate electrode embedded in an insulating layer that overlies a substrate, a gate dielectric overlying the gate electrode, an active layer comprising a compound semiconductor material and overlying the gate dielectric, and a source electrode and drain electrode contacting end portions of the active layer. The gate dielectric may have thicker portions over interfaces with the insulating layer to suppress hydrogen diffusion therethrough. Additionally or alternatively, a passivation capping dielectric including a dielectric metal oxide material may be interposed between the active layer and a dielectric layer overlying the active layer to suppress hydrogen diffusion therethrough.
