Abstract

The present invention relates to a stripping solution composition for removing photoresist and transparent conductive film. More concretely, the present invention provides an organic acid transparent conductive film remover capable of removing the transparent conductive film of the semiconductor device and a stripping solution composition containing the remover, wherein the stripping solution composition comprises more than two components and is composed of organic amine and solvent. The composition may further comprise the glycol ether compound serving as segregation resistance agent. The composition of the present invention comprises organic acid transparent conductive film remover, so that transparent conductive film can be removed. And, the transparent conductive film remover comprises sulphur and can be used as antiseptics to prevent the metal wiring of the lower metal film from being corrupted, thus, under the condition of keeping the metal pattern made by the current LCD manufacturing procedure, the present invention is capable of removing the photoresist of the formed pattern and selectively or totally removing the clear electrode of the photoresist coated on the metal wiring and the clear electrode of the metal wiring.

Description

technical field [0001] The present invention relates to a stripping liquid composition used for stripping the photoresist used in the formation of metal wiring, especially a stripping liquid composition containing two or more components of organic amine and solvent, containing It is a transparent conductive film remover used to prevent metal wiring and remove part or all of the transparent conductive film deposited on metal wiring or photoresist (photoresist), and may further include a diol-based protic solvent for anti-segregation A stripper composition for removing transparent conductive films and resists. Background technique [0002] In manufacturing processes of semiconductor devices such as integrated circuits (ICs) and very large-scale integrations (VLSIs), and liquid crystal displays (LCDs), metal wiring is usually formed by applying a photolithography process. Furthermore, representative transparent conductive films ITO and IZO are deposited on the substrate, and g...
