Description

Technical Field

[0001] The invention relates to the field of surface treatment, and in particular to a glass post-polishing cleaning agent with protective ink and a use method thereof. Background Art

[0002] With the large-scale application of glass frosting technology in the electronics industry, the non-frosted surface of the glass basically relies on spraying or screen printing ink to isolate the frosting liquid for protection. At the same time, the protective ink can also play a good role in preventing the glass from being dented, scratched, and crushed, which also provides a good protective layer for the glass CMP process.

[0003] The glass CMP process, or glass chemical mechanical polishing, is a technology that uses a combination of chemical and mechanical methods to precisely grind and polish the surface of silicon wafers. It is the hardware foundation of this technology that can achieve global flattening of the silicon wafer surface and provide a good foundation for subsequent processes. The CMP process includes three main steps: polishing, cleaning, and transfer. During the polishing process, the chemical components in the polishing liquid react with the material on the surface of the wafer to form a thin film that can be mechanically removed. The polishing pad then removes this thin film through mechanical action, thereby achieving a smooth surface.

[0004] At present, most glass needs to go through the CMP process before frosting. At the same time, there must be no polishing powder and polishing debris left after CMP cleaning, otherwise it may affect the use effect and life of the frosting liquid. After normal CMP processing, there will be a lot of polishing powder left on the surface of the glass and protective ink. Because the ink itself has a large number of microporous structures, the specific surface area is larger, resulting in more polishing powder residue and stronger adsorption, which also increases the difficulty of post-CMP cleaning in disguise. At the same time, the protective ink is made between processes and needs to be removed after frosting. This also requires that the adhesion of the ink should not be too large, otherwise it will increase the burden of subsequent removal and affect production efficiency.

[0005] Since most frosting protection inks are acid-resistant inks, their alkali resistance is not very good, which also makes most strong alkaline cleaning agents not suitable for post-CMP cleaning. Otherwise, it is easy to cause ink edge burning, sawtooth damage, partial shedding, etc., affecting the subsequent frosting quality. Therefore, it is imperative to develop a glass post-CMP cleaning agent, especially a cleaning agent that has a good cleaning effect on the polishing powder residue on the ink surface and is safe for ink and glass. Summary of the invention

[0006] The purpose of the present invention is to provide a glass post-polishing cleaning agent with protective ink to solve the problem of polishing powder and polishing debris remaining on the surface of glass and ink after glass chemical mechanical polishing.

[0007] The technical solution adopted by the present invention is as follows: According to one aspect of the present invention, a glass post-polishing cleaning agent with protective ink is provided, which is composed of the following components in mass percentage: 6-12% inorganic base, 5-10% pH buffer, 4-9% dispersant, 2-5% corrosion inhibitor, 3-5% penetrant, 5-8% anionic surfactant, and the balance is water.

[0008] Furthermore, the inorganic base is at least one of sodium hydroxide, potassium hydroxide and lithium hydroxide.

[0009] Furthermore, the pH buffer is at least one of sodium acetate, potassium acetate, lithium acetate, and ammonium acetate.

[0010] Furthermore, the dispersant is at least one of pentasodium aminotrimethylene phosphate, tetrasodium hydroxyethylidene diphosphate, sodium ethylenediaminetetramethylene phosphate, and sodium polyepoxysuccinate.

[0011] Furthermore, the corrosion inhibitor is at least one of zinc sulfate, zinc acetate, zinc chloride and zinc oxide.

[0012] Furthermore, the penetrant is at least one of isooctyl alcohol polyether monophosphate, fatty alcohol polyoxyalkyl ether, and isomeric decanol polyether phosphate.

[0013] Furthermore, the anionic surfactant is at least one of sodium cocoate, disodium fatty alcohol polyoxyethylene ether sulfosuccinate, and coconut oil alkyl alcohol amide phosphate.

[0014] At room temperature, the components are sequentially mixed, stirred and dissolved according to mass percentage to obtain a concentrated solution of a glass post-polishing cleaning agent with protective ink.

[0015] The principle of the present invention is as follows: The inorganic base used in the present invention is a strong inorganic base such as sodium hydroxide, potassium hydroxide, lithium hydroxide, etc., whose hydroxide ions can be completely ionized in water, providing a high pH environment for the cleaning agent; the pH buffer acetate uses a strong base and a weak acid salt, and the hydrolysis reaction generates acetate ions and hydroxide ions, and it is a reversible reaction. When the hydroxide ions in the solution increase, the acetate hydrolysis is inhibited and the reaction proceeds in the reverse direction. The acetate will consume part of the hydroxide to achieve the buffering pH effect, thereby preventing the high pH cleaning agent from corroding the glass and the ink, and preventing the glass from being scratched and blurred, and the ink from having burnt edges, sawtooth damage, and falling off.

[0016] The corrosion inhibitor used in the present invention is zinc salt such as zinc sulfate, zinc acetate, zinc chloride, zinc oxide, etc. Under alkaline conditions, the zinc salt can quickly form zinc hydroxide to deposit a very thin protective film on the surface of glass and ink, which plays a certain protective role. In addition, since the film layer has poor durability, it will also dissolve in alkaline media, so there is no problem of residual zinc hydroxide after cleaning.

[0017] The penetrants used in the present invention are all highly permeable alkali-resistant penetrants such as isooctyl alcohol polyether monophosphate, fatty alcohol polyoxyalkyl ether, and isomeric decanol polyether phosphate. Their molecular structures contain a large number of hydrophilic groups and hydrophobic groups, which also enable them to form a good adsorption layer at the solid-liquid or liquid-liquid interface, reduce the surface tension of the liquid surface, and enable the cleaning agent to quickly penetrate the solid surface, thereby achieving the effect of dispersing and softening solid dirt. The dispersant used mainly contains phosphonic acid groups and carboxylic acid groups, which can be quickly adsorbed on the surface of solid particles, making the surface of the condensed particles easy to wet, increasing the surface charge of the solid particles, and utilizing the electrostatic repulsion to loosen the particle dirt. Combined with the softening effect of the penetrant, it is easy to remove solid particles such as polishing powder and polishing debris on the surface of glass and ink.

[0018] The anionic surfactant used in the present invention is a carboxylate, sulfonate and phosphate anionic surfactant with good alkali resistance. Since most of the polishing powder is metal oxide particles such as cerium oxide and aluminum oxide, it is easy to adsorb cations and become positively charged. The anionic surfactant is easy to form negatively charged micelles after dissolving and ionizing in water. It can well adsorb the positively charged polishing powder particles to make them condense to form floccules, and the polishing powder is stripped and removed from the surface of glass and ink.

[0019] Another aspect of the present invention provides a method for using a glass post-polishing cleaning agent with protective ink, the steps comprising: (1) Take the above-prepared concentrated solution of the glass post-polishing cleaning agent with protective ink, add water at a mass percentage of 5-15% to obtain a cleaning working solution for later use; (2) Heat the diluted cleaning solution, control the temperature at 50-60°C, then place the glass workpiece to be cleaned into the cleaning solution and perform ultrasonic cleaning for 5-10 minutes; (3) Rinse the cleaned glass workpiece with pure water until no chemical residue is left, and then dry it to complete the cleaning.

[0020] Compared with the prior art, the present invention has the following advantages: 1. The post-polishing cleaning agent for glass with protective ink provided by the present invention adopts the combination of inorganic alkali and pH buffer to play a good pH buffering role, which reduces the risk of corrosion damage to glass and ink caused by the high pH of the inorganic alkali, and at the same time, the corrosion inhibitor plays a good protective effect on the glass and ink. The combination of penetrant and dispersant can well loosen and soften the particle dirt such as polishing powder and polishing debris, and the adsorption and flocculation effect of the anionic surfactant has a good removal effect on the particle dirt remaining in the micropores of the ink;

[0021] 2. The cleaning agent provided by the present invention has a simple preparation process, is easy to use, has safe and environmentally friendly ingredients, does not cause harm to human health and the environment, and meets the needs of environmentally friendly safety production.
