Abstract:
A method for manufacturing a thin film transistor display panel is provided to decrease the number of manufacturing processes and reduce a manufacturing cost, by forming pixel electrodes along with the gate lines using one mask. Undercut portions of photoresist portions are removed to form photoresist portions having reduced thicknesses and boundaries that are the same as those of underlying data lines(171) and drain electrodes(175), by using an etch-back process. Exposed impurity semiconductor layers are removed using the photoresist portions as an etch mask to form ohmic contacts(163a,165a), and then the photoresist portions are removed. The boundaries of the data lines and drain electrodes are the same as those of the ohmic contacts and a semiconductors(154a). A first insulating layer and a second insulating layer are deposited and etched to form an insulating pattern including column spacers and a passivation layer(180).

Abstract:
A method for manufacturing a thin film transistor substrate is provided to have no additive photolithographic process for forming a pixel electrode, thereby simplifying the manufacturing process, by simultaneously forming the pixel electrode and a gate line. A transparent conductive layer is formed on a substrate(110). A conductive layer is formed on the transparent conductive layer. A first photoresist film is formed on the conductive layer. The conductive layer is etched by using the first photoresist film as a mask with a first etching solution. The transparent conductive layer is etched by using the first photoresist film as a mask with a second etching solution, thereby forming a pixel electrode(191). A second photoresist film is formed on the first photoresist film. An exposed portion of the conductive layer is removed by using the second mask as a mask with the first etching solution, thereby forming a gate line having a gate electrode(124). A gate insulating layer(140), a semiconductor layer(154), a data line, drain and source electrodes(173,175), and a passivation layer(180) are sequentially formed by performing subsequent processes.

A chamber(100) includes a space on which a glass substrate(P) is placed, and a nozzle for spraying a process liquid onto the glass substrate. A transfer unit(17) transfers the glass substrate through the chamber. An inclined support(310) is received on the transfer unit and slopes the glass substrate mounted on its upper portion. An ozone reactor injects ozone to the process liquid which is sprayed onto the glass substrate. A degassing unit removes ozone contained in the process liquid. The degassing unit sprays nitrogen. The transfer unit is a conveyer which is horizontally moved. The glass substrate is sequentially passed through a plurality of baths. The chamber is divided into one or more partitions and includes the plurality of baths including the nozzles.

Abstract:
A substrate processing apparatus is provided to extend the lifetime of etchant by removing the metal ions remaining in the etchant by an absorption part. A wet etching part(210) etches a metal layer formed on a substrate by using etchant. An absorption part(220) absorbs the metal ions remaining the etchant, including an absorbing agent made of a mesoporous molecular sieve. The etchant passing through the absorption part is stored in a storage part(230). The etchant stored in the storage part is supplied to the wet etching part by a pump part(250). Etch residue in the etchant is filtered by the absorption part. The etchant stored in the storage part is exhausted by an exhaust part(260).
