Abstract:
An etch stop layer (ESL) thin-film transistor (TFT) substrate includes an active layer including a channel zone and two opposite side zones that are made conducting through treatment with plasma doping so that a distance between the two side zones is a width of the channel zone that is smaller than a distance between a source electrode and a drain electrode in electrical connection with the two opposite side zones respectively, so as to make a relatively small actual channel length. Such a relatively small actual channel length provides the TFT with an excellent electrical conduction property and has an advantage of increasing a source-drain current.

Claim (Index 1):
An etch stop layer (ESL) thin-film transistor (TFT) substrate, comprising:\n a backing plate, a gate electrode arranged on the backing plate, a gate insulation layer arranged on the gate electrode and the backing plate, an active layer arranged on the gate insulation layer and located above and corresponding to the gate electrode, an etch stop layer arranged on the active layer, and a source electrode and a drain electrode arranged on the etch stop layer; wherein the active layer is formed of a material that comprises a metal oxide semiconductor; the active layer has two opposite side zones that are respectively a source contact zone and a drain contact zone having increased electrical conductivity through plasma doping treatment, such that an area between the source contact zone and the drain contact zone of the active layer defines a channel zone; the etch stop layer is provided with a first via and a second via that are formed in the etch stop layer and respectively corresponding to the source contact zone and the drain contact zone of the active layer, the source electrode and the drain electrode being set in contact engagement with the source contact zone and the drain contact zone, respectively, through the first via and the second via; and the channel zone has a width that is smaller than a distance between the source electrode and the drain electrode; wherein the gate electrode has a width that is greater than or equal to a width of the active layer that includes the channel zone, the source contact zone, and the drain contact zone, such that two opposite side edges of the active layer are located inboard the gate electrode or are substantially in alignment with two opposite side edges of the gate electrode.
