Abstract: A method for manufacturing a TFT(Thin Film Transistor) substrate is provided to pattern a data metal film through a wet etching process and a dry etching process. A gate insulating film and an active layer(140) are successively formed on a substrate(110) in which a gate wire is formed. A data metal film(150) in which the first to the third metal layers(151~153) are continuously laminated is formed on the active layer. The first photoresist pattern(160) in which a channel forming region has a thickness which is relatively thinner than other regions is formed on the data metal layer. The data metal layer and the active layer are etched by using the first photoresist pattern. The first photoresist pattern is etched, and the second photoresist pattern in which the channel forming region is opened is formed. A primary dry etching of the third metal layer of the channel forming region is performed by using the second photoresist pattern. Secondary dry etching of the second metal layer is performed, and tertiary dry etching of the first metal layer is performed by using the second photoresist pattern.

Abstract: A method for fabricating a TFT substrate is provided to avoid a skew phenomenon of a source/drain electrode by forming the source/drain electrode by a dry etch process. A gate interconnection, a gate insulation layer, an active layer, a conductive layer for a data interconnection, and a photoresist pattern composed of first and second regions are sequentially formed on an insulation substrate(10). By using the photoresist pattern as an etch mask, the conductive layer for the data interconnection is etched to form a conductive pattern for a source/drain electrode(65,66) and a data line(62). By using the photoresist pattern as an etch mask, the active layer is etched to form an active layer pattern. The second region of the photoresist pattern is removed. By employing etch gas and using the photoresist pattern as an etch mask, the conductive layer pattern for the source/drain electrode under the second region is dry-etched. A part of the active layer pattern is etched by using the photoresist pattern as an etch mask. Reaction byproducts of the conductive layer pattern for the source/drain electrode are physically removed by a reaction byproducts removing agent so that external force is applied to the etch gas and the reaction byproducts. The photoresist pattern is stripped, and a passivation layer(70) and a pixel electrode are formed.
