Abstract
A semiconductor device includes an insulating substrate, a polysilicon layer, a first-gate-insulating layer, a first metal layer, an oxide-semiconductor layer, a second-gate-insulating layer, a second metal layer, a first insulating interlayer, a third metal layer, a first top gate planar type thin film transistor in which the polysilicon layer serves as a channel, and a second top gate planar self-aligned type thin film transistor in which the oxide-semiconductor layer serves as a channel. The gates of the first top gate planar type thin film transistor and the second top gate planar self-aligned type thin film transistor are made of the first and second metal layers, respectively. The sources and the drains of the first top gate planar type thin film transistor and the second top gate planar self-aligned type thin film transistor are made of the third metal layer.
