Abstract:
1. A thin film transistor (TFT) structure, comprising: a substrate, having a first surface and a second surface opposite to each other, wherein the first surface has a patterned mask layer thereon; a patterned first electrode layer, disposed on the second surface, having a gate portion and a capacitor electrode portion, wherein the patterned first electrode layer and the patterned mask layer are disposed on two opposite sides of the substrate; a patterned second electrode layer, disposed on the second surface, having a source and a drain, wherein the patterned second electrode layer is self-aligned with the patterned first electrode layer by exposing the first surface through using the patterned mask layer as a mask; and an insulating layer, disposed between the patterned first electrode layer and the patterned second electrode layer.
