Abstract:
1. A semiconductor structure, disposed on a substrate, and comprising: a gate electrode, disposed on the substrate; a gate insulating layer, disposed on the substrate, and covering the gate electrode; a channel layer, disposed on the gate insulating layer and located above the gate electrode, wherein the channel layer has a channel length L along a channel direction and has a first side and a second side opposite to the first side; a source electrode and a drain electrode, located at the two opposite sides of the channel layer, and electrically connected to the first side and the second side of the channel layer, respectively; a dielectric layer, covering the source electrode, the drain electrode and the channel layer; and a conductive light-shielding pattern layer, disposed on the dielectric layer, and overlapped to a portion of the source electrode and a portion of the channel layer in a vertical projection, wherein the conductive light-shielding pattern layer does not overlap to the drain in the vertical projection, and the conductive light-shielding pattern layer and the channel layer have an overlapping length d
