    摘要: Provided are a thin-film transistor (TFT) substrate and a method of manufacturing the same. The method includes: forming a passivation film by forming an insulating film on a substrate; forming a photoresist pattern by forming a photoresist film on the passivation film, exposing the photoresist film to light, and developing the photoresist film; performing a first dry-etching by dry-etching the passivation film using the photoresist pattern as an etch mask; performing a baking to reduce a size of the photoresist pattern; performing a second dry-etching to form a contact hole by dry-etching the passivation film again using the photoresist pattern as a mask; removing the photoresist pattern; and forming a pixel electrode of a carbon composition that includes carbon nanotubes and/or graphene on a top surface of the passivation film.

    摘要: A method of forming a metal pattern on a display substrate includes blanket depositing a copper-based layer having a thickness between about 1,500 Å and about 5,500 Å on a base substrate, and forming a patterned photoresist layer on the copper-based layer. The copper-based layer is over-etched by an etching composition containing an oxidizing moderating agent where the over-etch factor is between about 40% and about 200% while using the patterned photoresist layer as an etch stopping layer, and where the etching composition includes ammonium persulfate between about 0.1% by weight and about 50% by weight, includes an azole-based compound between about 0.01% by weight and about 5% by weight and a remainder of water. Thus, reliability of the metal pattern and that of manufacturing a display substrate may be improved.
