Abstract:
1. A thin film transistor, comprising: a gate disposed on a substrate and having a first lateral surface connecting the substrate; a gate insulating layer having a second lateral surface conformally formed on the first lateral surface of the gate; a semiconductor layer disposed on the gate insulating layer, wherein the semiconductor layer has an inclined surface conformally formed on the second lateral surface of the gate insulating layer such that the first lateral surface, the second lateral surface and the inclined surface constitute a conformally stacked structure; and a source and a drain respectively disposed on the semiconductor layer, located at two opposite sides of the conformally stacked structure of the first lateral surface, the second lateral surface of the inclined surface, wherein the source is spaced apart from the drain by a gap exposing the inclined surface of the semiconductor layer, and the inclined surface of the semiconductor layer interconnects the source and the drain.
