Description

Cleaning liquid composition and cleaning method of panel using same

The present invention relates to a cleaning liquid composition and a cleaning method using the same. The present invention relates to Korean Patent Application Nos. 10-2009-0069505 and 10-2009-0069506 filed to the Korean Patent Office on July 29, 2009, and Korean Patent Application No. Claims the benefit of the filing date of 10-2009-0073683, the entire contents of which are incorporated herein.

A flat panel display device (hereinafter referred to as "FPD") represented by a liquid crystal display device, like a semiconductor device, is manufactured through a process such as film formation, exposure and etching. However, when such a process is performed, very small particles having a size of 1 μm or less of various organic materials or inorganic materials may be attached to the surface of the substrate. When the following steps are carried out with these particles attached, pinholes or pits of the film, disconnection or bridges of the wires are generated, and the production yield of the product is lowered.

Thus, cleaning to remove particles is performed between each process. Many proposals have also been made for cleaning liquids for cleaning. For example, Japanese Laid-Open Patent Publication No. 2005-154558 proposes a cleaning liquid containing H ₃ PO ₄ , HF, ammonia, and / or an amine. However, the cleaning liquid of this patent cannot be used for cleaning FPD substrates because it contains a glass substrate, which is the most representative FPD substrate, and HF, which intensively etches Al, the most representative wiring material. . In addition, Japanese Patent Application Laid-Open No. 2000-232063 proposes to use phosphoric acid and ammonium phosphate as corrosion inhibitors. However, this patent is for removing resist residues and the pH of the composition is in the acidic range. Therefore, it is difficult to satisfy both the removal of very small particles having a size of 1 μm or less, which is a basic characteristic of the initial stage of cleaning, and the corrosion protection of aluminum wiring. In addition, Korean Patent Publication No. 10-0574607 proposes a cleaning solution containing deionized water, an organic compound and an ammonium compound in an acidic pH environment. However, since the cleaning solution of this patent is an acidic solution, the removal ability of very small particles having a size of 1 μm or less, such as organic or inorganic substances, which is a basic characteristic of the initial stage of cleaning, is not excellent. In addition, Korean Patent Publication No. 10-0599849 discloses an organic acid such as urea and / or an alkaline component such as urea urea, quaternary ammonium hydroxide, ammonia, citric acid (CITRIC ACID), malic acid (MALIC ACID), and tartaric acid (TARTARIC ACID). And / or a salt thereof, and a washing liquid containing residual deionized distilled water. However, the cleaning solution of this patent may cause the problem of precipitation of urea or ethylene urea with prolonged use.

An object of the present invention is to provide a cleaning liquid composition suitable for removing particles such as organic or inorganic substances present on a substrate used in a flat panel display.

It is also an object of the present invention to provide a cleaning liquid composition which does not corrode wiring including copper and wiring including aluminum used in a flat panel display.

The present invention relates to a total weight of the composition, (a) 0.05 to 5% by weight of an amine compound represented by any one of the following Formulas 1 to 5; (b) 0.01 to 10% by weight of an additive including one or two or more selected from the group consisting of an azole compound, an alkanol amine salt, and a reducing agent; And (c) provides a cleaning liquid composition for a flat panel display comprising a residual amount of water.
