Definitions
- the present invention relates to a positive resist processing liquid composition for preventing contamination sources such as polishing debris from adhering to the surface of a positive resist that is a surface protective film of a wafer in a manufacturing process for polishing a peripheral portion of a semiconductor substrate. And a positive resist developer that prevents the resist pattern from collapsing during rinsing and drying in the development process.
- a process of polishing a peripheral portion of a substrate such as a semiconductor wafer there is a process of polishing a peripheral portion of a substrate such as a semiconductor wafer (see, for example, Patent Document 1).
- RIE Reactive Ion Etching
- this process for example, in the RIE (Reactive Ion Etching) process in which trench capacitor trenches (deep trenches) are formed on the surface of the Si wafer, by-products generated during etching are attached to the bevel and edge portions of the Si wafer.
- this is a step of polishing and removing the needle-like projections formed by acting with an etching mask with a polishing tape or the like to which abrasive grains are applied. Needle-shaped protrusions must be removed because they are damaged when transporting wafers, etc., causing dust generation and reducing the yield.
- Patent Document 3 discloses a resist pattern forming method using TMAH (tetramethylammonium hydride mouth oxide), jetylethanol as a hydrophilic treatment agent having excellent developer wettability.
- TMAH tetramethylammonium hydride mouth oxide
- a method for improving hydrophilicity by supplying an aqueous solution of amine or the like to the surface of a positive resist for several minutes by supplying these hydrophilic treatment agents is disclosed.
- the hydrophilization treatment takes time and the throughput is problematic.
- a surfactant or a water-soluble polymer agent is supplied to the substrate surface by supplying a surfactant or a water-soluble polymer agent to the substrate surface in advance when polishing the peripheral edge of the treated substrate.
- a method of applying a coating to prevent particles from adhering to the substrate surface is disclosed.
- the surfactant and water-soluble polymer are removed by supplying pure water to the substrate surface, and the coating effect is lost. Therefore, the surfactant is supplied continuously or intermittently during the polishing process. This is uneconomical because a large amount of processing solution is required.
- Hydrophilization of the positive resist surface can be achieved by slightly dissolving the surface with a general organic alkaline solution such as TMAH or choline. While rotating the wafer using a single wafer type apparatus, the wafer is rotated.
- a general organic alkaline solution such as TMAH or choline.
- the amount of treatment liquid required is large due to the large surface tension of the above-mentioned organic alkali solution, and wetting spreads. Due to the inferior property, there is a problem that the treatment liquid does not spread uniformly over the entire surface of the wafer and the hydrophilicity becomes insufficient.
- a positive resist pattern and a rinsing liquid for example, water
- rinsing and drying There is a concern that the pattern collapses due to the interfacial tension between them.

- An object of the present invention is a processing liquid composition capable of uniformly imparting hydrophilicity to the entire surface of a positive resist, and in particular, a surface protective film in a manufacturing process for polishing a peripheral portion of a semiconductor substrate.
- a processing liquid composition capable of uniformly imparting hydrophilicity to the entire surface of a positive resist, and in particular, a surface protective film in a manufacturing process for polishing a peripheral portion of a semiconductor substrate.
- Another object of the present invention is to reduce the interfacial tension acting between the positive resist and water during rinsing and drying by making the surface of the positive resist hydrophilic during development.
- An object of the present invention is to provide a developer capable of preventing the collapse of the film.
- R and R each represent a methyl group, R represents an alkyl group having 12 to 18 carbon atoms;
- a positive type resist comprising an aqueous solution containing a quaternary ammonium hydroxide represented by The present invention relates to a treatment liquid composition.
- the present invention also relates to a positive resist surface treatment method for treating a positive resist surface using the positive resist treatment liquid composition.
- the present invention relates to the positive resist surface treatment method, wherein the positive resist surface is treated in advance using the positive resist treatment liquid composition when polishing a peripheral portion of a semiconductor substrate.
- the present invention also relates to the positive resist surface treatment method, wherein the treatment is carried out by spraying, dropping, or dipping.
- the present invention relates to a positive resist developer comprising an aqueous solution containing the quaternary ammonium hydroxide represented by the above general formula (I).
- the positive resist processing liquid composition of the present invention contains a quaternary ammonium hydroxide having an alkyl group having 12 to 18 carbon atoms and a hydroxyl group, and has excellent surface tension lowering ability.
- the treatment liquid composition can be uniformly applied to the substrate. Further, since the permeability to the resist is increased, it is possible to dissolve the positive resist surface within a range of several tens of A to several hundreds of A in a short time, thereby promoting hydrophilicity. Furthermore, in the case of processing with the positive resist processing liquid composition of the present invention, once the hydrophilicity is achieved, the effect is sustained, and the coating effect is not lost by supplying pure water or polishing liquid to the substrate surface.
- hydrophilization means imparting hydrophilicity to the resist surface, and hydrophilization can be evaluated by so-called wettability. For example, after supplying pure water to the substrate surface, it is possible to evaluate by the force that water on the resist surface is repelled (hydrophobic) or the entire resist surface is kept wet (hydrophilicity).
- the positive resist processing liquid composition of the present invention exhibits the above excellent effects by containing the quaternary ammonium hydroxide represented by the above general formula (I).
- TMAH is a general organic alkali choline (whether R to R in general formula (I) are all methyl groups)
- the surface tension is small, so the amount of treatment liquid composition required is smaller than these organic alkalis, and the substrate is not damaged because it is weakly alkaline.
- the inventors of the formula have R of 8 carbon atoms.
- the positive resist developer of the present invention reduces the interfacial tension acting between the positive resist and the rinse liquid (for example, water) during rinsing and drying by making the positive resist surface hydrophilic. Therefore, the resist pattern can be prevented from collapsing.
- the rinse liquid for example, water
- the developer of the present invention imparts wettability to the resist surface, the developer covers the entire substrate surface and also has an effect of suppressing the occurrence of uneven development.
- the surface of the positive resist serving as a surface protective film is short. Since hydrophilicity can be imparted over time, and the imparted hydrophilicity lasts, adhesion of particles to the surface of the positive resist can be prevented only by supplying pure water during polishing, contributing to an improvement in throughput. In addition, since the surface tension of the treatment liquid composition is small, the amount of the treatment liquid composition used in hydrophilizing the positive resist surface can be reduced, and the force to uniformly apply to the substrate can be reduced. Further, according to the positive resist developer of the present invention, the resist surface is hydrophilized along with the development of the positive resist, so that the resist pattern can be prevented from collapsing during drying.
- the treatment liquid composition of the present invention is a treatment liquid capable of imparting hydrophilicity to the positive resist surface, and is represented by the following general formula (I): a methyl group having 12 to 12 carbon atoms. Containing quaternary ammonium hydroxide having 18 alkyl groups and hydroxyethyl groups;
- R and R each represents a methyl group, R represents an alkyl group having 12 to 18 carbon atoms;
- R may be linear or branched, but is preferably linear
- Preferred examples of the quaternary ammonium hydroxide represented by the general formula (I) include 2-hydroxyethyl (N, N dimethyl and N lauryl) ammonium hydride represented by the following formula (la): Oxide, 2-hydroxyethyl (N, N dimethyl-N myristyl) ammonium hydroxide represented by formula (lb), 2-hydroxyethyl (N, N dimethyl-N stearyl) represented by formula (Ic) Ammoniumhide mouth oxide etc. are mentioned.
