Abstract: A thin film transistor includes a gate electrode, an active pattern overlapping with the gate electrode and including a semiconductive oxide, and a source metal pattern disposed on the active pattern and including a source electrode and a drain electrode spaced apart from the source electrode. The active pattern underlaps an entire portion of a lower surface of the source metal pattern and minimally protrudes beyond lateral ends of the source metal pattern due to the active pattern having sidewall taper angles that are substantially greater than corresponding and adjacent sidewall taper angles of the overlying source metal pattern. Thus parasitic capacitance may be reduced and performance enhanced.

Abstract: A substrate-treating apparatus includes a liquid-providing part, a first liquid-removing knife and a returning part. The liquid-providing part provides a first liquid chemical for cleaning a substrate that includes a metal pattern and a photoresist pattern on the metal pattern, and for removing an etchant that remains on the substrate. The first liquid-removing knife sprays a second liquid chemical in a direction inclined and opposite to a returning direction of the substrate, so as to remove the first liquid chemical, the first liquid chemical including a metal precipitate. The returning part returns the substrate from the liquid-providing part toward the first liquid-removing knife in the returning direction.

Abstract: A method of forming a metal pattern includes disposing a gate metal layer on a substrate; disposing a photoresist layer on the gate metal layer; etching portions of the photoresist layer to form a first photo pattern; etching portions of the gate metal layer to form a gate pattern including a gate electrode, in which the gate metal layer is patterned using the first photo pattern as a mask; ashing an end portion of the first photo pattern to form a second photo pattern; disposing a first gate insulating layer over the substrate and the second photo pattern; removing the second photo pattern and a portion of the first gate insulating layer disposed over the second photo pattern; and disposing a second insulating layer over the gate pattern and the remaining portions of the first gate insulating layer.
