Definitions
- the present invention relates to a cleaning composition in a semiconductor manufacturing process, and in particular to a photoresist cleaning composition.
- a photoresist coating is first formed on a surface of a metal such as silicon dioxide, Cu (copper), or a low-k material, and exposed and developed using a suitable mask, depending on the photoresist used.
- the photoresist is removed from the exposed or unexposed portions, a photoresist pattern is formed at a desired portion, and then plasma etching or reactive gas etching is performed on the photoresist pattern to perform pattern transfer.
- the low temperature and fast cleaning process is an important direction for the development of semiconductor wafer fabrication processes. Negative photoresists with thicknesses above 20 ⁇ are gradually being used in semiconductor wafer fabrication processes.
- the negative photoresist having a cross-linked network structure after exposure and etching is especially a thick film negative photoresist.
- cleaning agents In the chemical cleaning of photoresists on semiconductor wafers, cleaning agents often cause corrosion of the wafer pattern and substrate. Especially in the process of removing photoresist and etching residues by chemical cleaning agents, corrosion of metals (especially active metals such as aluminum and copper) is a common and very serious problem, which often leads to a significant decrease in wafer yield. .
- the photoresist cleaning composition is mainly composed of a strong base, a polar organic solvent and/or water, etc., and the photoresist on the semiconductor wafer is removed by immersing the semiconductor wafer in a cleaning agent or rinsing the semiconductor wafer with a cleaning agent.
- Strong bases such as potassium hydroxide, quaternary ammonium hydroxides and alcohol amines, etc., are capable of dissolving the photoresist residues produced by the photoresist and/or etching.
- the cleaning agent When the content of the strong base is too low, the cleaning agent has insufficient ability to remove the photoresist residue generated by the photoresist and/or the etching; however, when the content of the strong alkali is too high, the cleaning agent is liable to cause corrosion of the wafer pattern and the substrate.
- a cleaning agent containing potassium hydroxide or a quaternary ammonium hydroxide has a better ability to remove photoresist residues generated by photoresist and/or etching than a cleaning agent composed of an alcohol amine.
- the cleaning agent of potassium hydroxide is liable to cause corrosion of the wafer pattern and the substrate, and the removal of the photoresist is mainly in a peeling manner, so that the photoresist forms a chip-like peeling or a gel-like swelling, which easily causes the photoresist. Deposition or adhesion on the surface of the wafer, even leading to damage to the wafer pattern.
- the cleaning agent containing the quaternary hinge hydroxide has both stripping and dissolving effects on the photoresist, and does not cause deposition or adhesion of the photoresist on the surface of the wafer.
- the polar organic solvent is capable of dissolving the photoresist residues generated by the photoresist and/or etching, and improving the cleaning ability of the chemical cleaning agent for organic substances.
- the cleaning agent has insufficient ability to remove the photoresist residue generated by the photoresist and/or the etching; but when the content of the polar organic solvent is too high, the strong alkali content in the cleaning agent Correspondingly, the ability of the cleaning agent to remove photoresist residues from photoresist and/or etching is reduced.
- a photoresist cleaning agent composed of an alkanolamine and an organic polar solvent is proposed in US 4,761,251.
- the semiconductor wafer was immersed in the cleaning agent, and the positive photoresist on the wafer was removed at 95 °C.
- the cleaning agent does not contain water, and its cleaning ability for negative photoresist is insufficient.
- a photoresist cleaning agent composed of an alcohol amine, a water-soluble organic solvent, water, an organic phenol compound, a triazole compound, and a silicone antimony surfactant is proposed in U.S. Patent No. 6,140,027.
- the semiconductor wafer is immersed in the cleaning agent, and the photoresist on the wafer and the photoresist residue generated by the etching are removed at 20 to 50 °C.
- the cleaning agent uses an organic phenol compound and a triazole compound as corrosion inhibitors for inhibiting metal corrosion.
- Organic phenolic compounds are harmful to the human body and cause environmental pollution.
- the cleaning agent has insufficient cleaning ability for the negative photoresist.
- Lithography consisting of potassium hydroxide, propylene glycol ether, N-methylpyrrolidone, surfactant, 1,3-butanediol, diglycolamine and water in an amount of less than 1% by mass is proposed in US Pat. No. 5,962,197.
- Glue cleaner The semiconductor wafer is immersed in the cleaning agent, and the photoresist on the wafer is removed at 90 to 110 °C.
- the cleaning agent contains potassium hydroxide, which has high corrosion to the wafer substrate and is formed by stripping the photoresist.
- the flaky exfoliate or colloidal swell may deposit or stick on the surface of the wafer, causing residue of the photoresist and damage to the wafer pattern.
- a photoresist cleaning agent consisting of tetramethylammonium hydroxide, N-methylmorpholine-N-oxide, water and 2-mercaptobenzimidazole is proposed in WO2004059700.
- the semiconductor wafer was immersed in the cleaning agent, and the photoresist on the wafer was removed at 70 °C.
- the cleaning agent uses N-methylmorpholine-N-oxide as an oxidizing agent and 2-mercaptobenzimidazole as a metal corrosion inhibitor.
- the cleaning agent needs to clean the photoresist at a higher temperature, and the etching of the semiconductor wafer pattern and the substrate is slightly higher, and the cleaning ability of the photoresist is slightly insufficient.
- a photoresist cleaning agent consisting of quaternary ammonium hydroxide, dimethyl sulfoxide, 1,3,-dimethyl-2-imidazolidinone and water is proposed in U.S. Patent No. 6,040,117.
- the semiconductor wafer is immersed in the cleaning agent, and a photoresist having a thickness of ⁇ or more on the metal (gold, copper, lead or nickel) substrate is removed at 40 to 95 °C.
- the cleaning agent uses 1,3'-dimethyl-2-imidazolium, which is relatively expensive, as an organic co-solvent, and does not contain a corrosion inhibitor that inhibits corrosion of metals, especially active metals such as aluminum.
- the cleaning agent needs to clean the photoresist at a relatively high temperature, and the etching of the semiconductor wafer pattern and the substrate is slightly higher.
- a photoresist cleaning agent composed of a quaternary ammonium hydroxide, a water-soluble organic solvent, an organic amine, a dihydric alcohol, and water is proposed in JP2001215736.
- the semiconductor wafer was immersed in the cleaning agent, and a photoresist having a thickness of 20 ⁇ m to 40 ⁇ m on the wafer was removed at 20 to 90 °C.
- the cleaning agent uses a glycol as a corrosion inhibitor for inhibiting metal corrosion, but the diol has a weak ability to inhibit metal corrosion and reduces the cleaning ability of the cleaning agent for the photoresist, especially the negative photoresist.
- the cleaning agent has a slightly higher corrosion of the semiconductor wafer pattern and the substrate.
- a photoresist cleaning agent consisting of quaternary ammonium hydroxide, ⁇ -methylpyrrolidone, diethanolamine or triethanolamine, water and methanol or ethanol is proposed in JP2004093678. Immersing the semiconductor wafer into the cleaning In the agent, a photoresist having a thickness of ⁇ or more on the wafer is removed at 15 to 80 °C.
- the cleaning agent uses methanol or ethanol as a solubilizer for the quaternary ammonium hydroxide, but the flash point of methanol or ethanol is too low, and the cleaning ability of the cleaning agent for the photoresist, especially the negative photoresist, is lowered.
- the cleaning agent does not contain a corrosion inhibitor that inhibits corrosion of metals such as more reactive metals such as aluminum and copper.
- the cleaning agent has a slightly higher corrosion of the semiconductor wafer pattern and the substrate.
- the existing photoresist cleaning agent has insufficient cleaning ability for a photoresist having a relatively high thickness, or is highly corrosive to a semiconductor wafer pattern and a substrate, and has a large defect.
- the technical problem to be solved by the present invention is to provide a kind of light for the defects that the existing photoresist cleaning agent has insufficient cleaning ability for the thick film photoresist, is highly corrosive to the semiconductor wafer pattern and the substrate, and is harmful to the environment.
- a photoresist cleaning composition which has strong cleaning ability and is less corrosive to semiconductor wafer patterns and substrates and is environmentally friendly.
- a photoresist cleaning composition comprising quaternary ammonium hydroxide, water, mercapto diol aryl ether, dimethyl sulfoxide and corrosion inhibitor, wherein At least one of the corrosion inhibitors is selected from the group consisting of citric acid, citrate, and citrate.
- the citric acid, citric acid ester and citrate are preferably selected from the group consisting of citric acid, 2-hydroxy citric acid, trimethyl citrate, triethyl citrate, tripropyl citrate, and lemon.
- citric acid 2-hydroxycitric acid, lauryl citrate, glyceryl citrate, ethanolamine citrate, triethanolamine citrate, diglycol citrate, tetramethylammonium citrate, citric acid
