摘要:
A method of producing a thin film transistor substrate to prevent an interconnection from being corroded during a dry etching process includes sequentially forming on an insulating substrate a gate interconnection, a gate insulating layer, an active layer, a conductive layer for a data interconnection, and a photoresist pattern including a first region and a second region, etching the conductive layer for the data interconnection using the photoresist pattern as an etching mask to form a conductive layer pattern for source/drain electrodes, etching the active layer using the photoresist pattern as the etching mask to form an active layer pattern, removing the second region of the photoresist pattern, dry etching the conductive layer pattern for the source/drain electrodes under the second region using the photoresist pattern as the etching mask and etching gas, etching a portion of the active layer pattern using the photoresist pattern as the etching mask, and physically removing the reaction byproduct using a reaction byproduct removal agent so that external force is applied to the etching gas and the reaction byproduct of the conductive layer pattern for the source/drain electrodes.
摘要:
A method of manufacturing a contact portion is provided, which includes: forming a first signal line on a substrate (110), forming a insulating layer (140) covering the first signal line and having a contact hole (182, 185) exposing the first signal line; forming a contact layer (700) on the exposed surface of the first signal through the contact hole; and forming a second signal line (82, 190) connected to the first signal line via the contact layer. Wherein the first signal line is made of Al or Al alloy, and the second signal line is made of ITO or IZO.
