When manufacturing an electronic component such as a semiconductor, a light-emitting diode, a solid-state imaging device, or a liquid crystal display, a planarizing film is formed on a permanent film on a substrate, and the substrate of the upper overlapping layer is processed by the planarizing film. For example, in order to solve the problem of wiring delay which is clear when the pattern specifications of the semiconductor device are made fine, a double-ripple step for using a method of forming wiring on a semiconductor substrate is reviewed while using copper as a wiring material. In the double corrugation step, the via holes are formed, and the substrate having a large aspect ratio forms an antireflection film. Therefore, the antireflection film used in this step requires the burying property of the gap-free boring hole and the flattening property of forming a flat film on the surface of the substrate. A method of forming such a film has been proposed (refer to Patent Document 专利, Patent Document 2, Patent Document 3). -5- 200944944 A permanent film such as an inorganic oxide film, an inorganic nitride film, or an inorganic oxynitride film is used for the substrate, and the photoresist is coated and exposed by a step of forming a wiring or the like on the permanent film. And the step of developing, so when the surface of the permanent film has irregularities, it needs to be flattened to prevent photo-anti-contact agent reflection. Further, in the solid-state imaging device and the liquid crystal display, when the microlens is formed on the color filter, a step of flattening the color filter is provided, and a microlens is formed on the planarization film.

Advantageous Effects of Invention The present invention provides a film forming composition for forming a flattening film used in the step of flattening a surface having irregularities by light irradiation -9-200944944. In the production of an electronic component, the film-forming composition of the present invention is applied onto a substrate by a coating method such as a spin coating method to form a coating film, and the film is cured by light irradiation. The step of heating at a low temperature may be added before or after the light irradiation. Since the film-forming composition of the present invention contains a photopolymerizable substance, a photopolymerization initiator, and a solvent, it can be impregnated on the uneven surface to form a flat surface during coating, and can be formed into a flat surface by photocuring after evaporating the solvent. Further, since the film-forming composition of the present invention retains fluidity after evaporating the solvent after coating, the photopolymerizable material to be used is preferably a liquid material at normal temperature and normal pressure. Since such a liquid substance remains in a liquid state after evaporating the solvent, it can penetrate the uneven surface and flatten the uneven surface, and then form a flat surface by photohardening. When the film-forming composition of the present invention is used as a photoresist base film for a semiconductor device, for example, an underlayer film capable of filling a hole formed in a semiconductor substrate without a gap can be obtained. Further, when the film-forming composition of the present invention is used as the underlayer film-forming composition, the underlayer film can be formed by light irradiation without heating at a high temperature. Therefore, it is possible to prevent contamination of peripheral devices due to volatilization or sublimation of low molecular weight components. Further, even if it is not required to be heated under high temperature, even if the underlying film composition is used in a low molecular weight component or sublimation, it can be used for a low-molecular-weight composition of an underlying film composition. Therefore, the underlayer film can be formed by forming the composition using the underlying film having a lower viscosity. An underlayer film having excellent hole chargeability and planarization of a semiconductor substrate can be formed. -10-200944944 BEST MODE FOR CARRYING OUT THE INVENTION The film-forming composition of the present invention contains a photopolymerizable substance and a composition for forming a flattening film used for the step of flattening a surface having irregularities by light irradiation.

In the above formula (1), G1 is a sugar skeleton, T is a divalent linking group, R1 is a vinyl group or a glycidyl group, and R2 is a hydrogen atom or a hydroxyl group. η and L are each independently an integer of 〇 or 1, and p is an integer of the total number of hydroxyl groups of the sugar. m is an integer satisfying ISmS (p-m). For example, the total number of hydroxyl groups of glucose, fructose, and galactose is five, so the total number of hydroxyl groups of P = 5 'trehalose, sucrose, lactose, maltose, and cellobiose is eight, so p = 8. -12-200944944 The R1 or TR1 is a photopolymerizable group which reacts with a hydroxyl group of a sugar, and when a hydroxyl group of a sugar is reacted with a photopolymerizable compound at a ratio of one or more, a photopolymerizable group-containing sugar compound can be obtained. The sugar compound is preferably a liquid, and is easily liquidified when the number of hydroxyl groups is small. Therefore, it is preferably a compound having 80% or more of the hydroxyl groups of the entire sugar, and preferably a compound having a total hydroxyl group of the sugar substituted by a photopolymerizable group. In the formula (1), τ is a carbonyl group, an alkyl group having 1 to 6 carbon atoms, an alkyl group having an alkyl group, a phenyl group, and the like.

The vinyl group-containing compound is, for example, a vinyl carboxylic acid, a vinyl carboxylic acid butanol ester, a vinyl carboxylic acid ethylene glycol ester, a vinyl carboxylic acid diethylene glycol ester, a vinyl carboxylic acid tetraethylene glycol ester or the like. When a glycidyl group-containing sugar is produced, the compound substitution method in the molecule can be obtained by dehydration condensation, that is, by reacting a sugar compound with an epihalohydrin. The epihalohydrin used in the reaction is, for example, epichlorohydrin, cyclodoxypropanepropane, iodopropylidene or the like, but it is preferably an industrially available and inexpensive oxychloropropane. This reaction can be carried out by a previously known method of obtaining a polyglycidyl ether from an epihalohydrin and a hydroxyl group.

The reaction may vary depending on the strength of the reactivity of the introduced compound, but the reaction time is preferably 30 minutes or longer, more preferably 30 to 3 minutes. A catalyst can be used to promote the reaction. The alkali metal hydroxide used in this case may be an aqueous solution by continuously adding the alkali metal hydroxide while continuously distilling off water and epoxy chlorine under reduced pressure or under normal pressure in the reaction system. The propane is re-distributed to remove the water and the epichlorohydrin is continuously returned to the reaction system.

Further, when the film-forming composition of the present invention is used for producing an antireflection film of a photoresist underlayer in a photolithography etching step of a semiconductor device, a polymer compound excellent in light absorption performance can also be used. The use of such a polymer compound' improves the performance of the film formed of the film-forming composition of the present invention as an antireflection film. When the polymer compound is used, the amount thereof may be, for example, 0.1 to 50 parts by mass based on 1 part by mass of the photopolymerizable substance. -26-200944944 The film-forming composition of the present invention is preferably used, and each component (hereinafter referred to as "solid component") of the photopolymerizable compound is dissolved in a solvent solution. The solvent to be used may be one which dissolves a solid component to form a homogeneous solution. For example, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, methyl cellosolve acetate, ethyl cellosolve acetate, diethylene glycol monomethyl ether, diethylene glycol one Ethyl ether, propylene glycol, propylene glycol monomethyl ether, propylene glycol monomethyl ether acetate, propylene glycol propyl ether acetate, toluene, xylene, methyl ketone ethyl ketone, cyclopentanone, cyclohexanone, 2 -ethyl hydroxypropionate, ethyl 2-hydroxy-2-methylpropionate, ethyl ethoxyacetate, ethyl hydroxyacetate, methyl 2-hydroxy-3-methylbutanoate, 3-methoxy Methyl propionate, ethyl 3-methoxypropionate, ethyl 3-ethoxypropionate, methyl 3-ethoxypropionate, methyl pyruvate, ethyl pyruvate, ethyl acetate, acetic acid Butyl ester, ethyl lactate, butyl lactate, N-dimethylformamide, N-dimethylacetamide, dimethyl submilling and N-methylpyrrolidone. These solvents may be used alone or in combination of two or more. The solvent to be used is preferably a solvent having a boiling point of 80 to 250 ° C, or 100 to 200 ° C, β or 120 to 180 ° C. When the boiling point of the solvent is low, a large amount of solvent is evaporated in the coating film-forming composition to increase the viscosity, resulting in a decrease in coatability. When the boiling point of the solvent is high, it takes time to dry after the coating film forms a composition. The solvent is used in an amount such that the solid content of the film-forming composition is, for example, 0.5 to 50% by mass, or 3 to 40% by mass, or 10 to 30% by mass. Next, a method of forming a composition using the film of the present invention of the photoresist underlayer film will be explained. For example, the film-forming composition of the present invention is applied to a semiconductor substrate for manufacturing a semiconductor device using a suitable coating method such as a spin coater or a bar coater (for example, a tantalum/cerium oxide-coated substrate, a tantalum wafer, or a niobium nitrogen). A coating film is formed on the substrate -27-200944944, the glass substrate, the ITO substrate, the polyimide substrate, and the low-permittivity material (low-k material-coated substrate). Further, before the light is applied to the coating film, a drying step may be carried out if necessary. When a composition is formed using a film containing a solvent, it is preferred to carry out a drying step. The drying step may be such that the method of heating at a high temperature is not particularly limited. However, when it is heated at a high temperature (e.g., a temperature of 1 50 ° C or more), it is estimated that the solid content contained in the coating film is sublimated or the like to contaminate the apparatus. Therefore, the drying step may be, for example, heating the substrate at 50 to 100 t on a hot plate for 1 to 1 minute. Also, for example, 'dry at room temperature (20 ° C). Next, the coated film was irradiated with light. The light irradiation may be a method in which the photopolymerization initiator acts to polymerize the photopolymerizable substance, and is not particularly limited. Light irradiation can be performed, for example, using light having a wavelength of 150 nm to 700 nm, or 193 to 700 nm, or 300 to 600 nm. The light irradiation can be performed, for example, by using an ultrahigh pressure mercury lamp, a flash UV lamp, a high pressure mercury lamp, a low pressure mercury lamp, a DEEP-UV (deep ultraviolet) lamp, a short arc arc metal halide lamp, a YAG laser excitation lamp, a xenon flash lamp, or the like. For example, when using an ultra-high pressure mercury lamp, it can be contained in the ultraviolet range 289 nm, 297 nm, 303 nm, 313 nm (j line), 334 nm, 365 nm (i line), and visible light field 405 nm (h line) ), the 436 nm (g line), 546 nm, and 579 nm wavelengths of the bright line spectrum of the peak wavelength of 150 nm to 700 nm are irradiated. The photopolymerization agent or the living radical is generated by the photopolymerization initiator in the coating film by light irradiation, and the photopolymerizable compound in the coating film is thereby subjected to a polymerization reaction. As a result of the polymerization, a film can be formed. The film to be formed may be, for example, a solvent used for the composition of the coated photo-catalyst -28-200944944, such as ethylene glycol monomethyl ether, when the photoresist is applied to the upper layer thereof. Ethyl cellosolve acetate, diethylene glycol monoethyl ether, propylene glycol, propylene glycol monomethyl ether, propylene glycol monomethyl ether acetate, propylene glycol propyl ether acetate, toluene, methyl ethyl ketone , cyclohexanol, ethyl 2-hydroxypropionate, ethyl 2-hydroxy-2-methylpropionate, ethyl ethoxyacetate, methyl pyruvate, ethyl lactate and butyl lactate Low things. Therefore, the film formed of the film-forming composition of the present invention does not mix into the photoresist.膜 The film-forming composition of the present invention is suitably used as shown in FIG. 1 and has an aspect ratio of pore depth (b) / diameter (e) of 1 or more, for example, 1 to 1 Å, or 2 to 5 pores. Semiconductor substrate. Further, the film-forming composition of the present invention can be used as a film for forming a film which does not have such a gap. Further, a semiconductor substrate (a substrate having a hole-tight portion and a hole-diffusing portion) having a dense hole having an aspect ratio of 1 or more is suitable for the film-forming composition of the present invention. The film-forming composition of the present invention can be used for forming a flat film on the surface of a substrate in which such a pore-like pore exists. Further, the film-forming composition of the present invention can be used for a semiconductor substrate having a hole having an aspect ratio smaller than G 1 or a semiconductor substrate having a step. The film thickness of the film formed of the film-forming composition of the present invention on the surface of the substrate may be, for example, 20 to 2000 nm, or 30 to 1000 nm, or 50 to 800 nm. A photoresist can be formed over the film formed from the film-forming composition of the present invention. Thus, a laminated structure of the underlayer film and the photo-induced uranium agent can be formed on the semiconductor substrate. To form a photoresist, a known method is employed in which a photoresist composition solution is applied onto an underlying film and heated. The photoresist formed on the film of the present invention is not particularly limited, and any of a general-purpose negative photoresist and a positive photoresist can be used. For example, a positive photoresist formed of phenol -29-200944944 varnish resin and 1,2-naphthoquinonediazide sulfonate, which is composed of a binder having a base which can be decomposed by an acid to increase the alkali dissolution rate and A chemically amplified photoresist formed by a photoacid generator, which is chemically strengthened by decomposition of a low molecular compound and an alkali soluble binder and a photoacid generator which can be decomposed by an acid to increase the alkali dissolution rate of the photoresist. Type photoresist, a low molecular compound and a photoacid generator which have a base which can be decomposed by an acid to increase the alkali dissolution rate, and which are decomposed by an acid to increase the alkali dissolution rate of the photoresist. The chemically amplified photoresist to be formed, for example, is commercially available under the trade name APEX-E, manufactured by Sumitomo Chemical Co., Ltd., and sold under the trade name PAR710 by Sumitomo Chemical Industries Co., Ltd., and under the trade name SEP R4 30 manufactured by Shin-Etsu Chemical Co., Ltd. Secondly, exposure is performed through a certain mask. KrF quasi-molecular laser (wavelength 248 nm), ArF excimer laser (wavelength 193 nm) and F2 excimer laser (wavelength 157 nm) can be used for exposure. Post exposure bake can be performed if necessary after exposure. The post-exposure heating can be suitably selected from a heating temperature of 70 ° C to 150 ° C and a heating time of 0.3 to 10 minutes. The development is then carried out using a developing solution. For example, when a positive photoresist 106 is used, the exposed portion of the photoresist can be removed at this time to form a pattern of the photoresist. The developing solution is an aqueous solution of an alkali metal hydroxide such as potassium hydroxide or sodium hydroxide, an aqueous solution of tetramethylammonium hydroxide, tetraethylammonium hydroxide, quaternary ammonium hydroxide such as choline, ethanolamine or propyl group. An alkaline aqueous solution such as an amine or an aqueous amine solution such as ethyldiamine. Further, a surfactant or the like may be added to these developing solutions. The development conditions can be appropriately selected from a temperature of 5 to 50 ° C and a time of 0.1 to 5 minutes. -30- 200944944 Thereafter, the thus formed photoresist pattern is used as a protective film to perform underlayer film removal and semiconductor substrate processing. When removing the underlayer film, tetrafluoromethane (CF4), perfluorocyclobutane (C4F8), perfluoropropane (c3f8), trifluoromethane, carbon monoxide, argon, oxygen, nitrogen, sulfur hexafluoride, difluoromethane, Gases such as nitrogen trifluoride and chlorine trifluoride are dry etched. The removal of the underlying film forms a pattern formed by the underlying film and the photoresist on the semiconductor substrate. Further, when the film-forming composition of the present invention is used for forming the underlayer film Φ, an anti-reflection film layer can be formed before the photo-induced uranium-repellent agent is formed over the underlayer film. The antireflection film is not particularly limited, and an existing antireflection film can be used. For example, a composition for forming an antireflection film which is conventionally used in the previous photolithography etching step is applied onto an underlayer film by a conventional method such as a spin coater or a bar coater, and then fired to form an antireflection film. The antireflection film composition is, for example, a main component is a light absorbing compound, a resin, and a solvent, and the main component is a resin having a light absorbing group linked by a chemical bond, a crosslinking agent, and a solvent, and the main component is a light absorbing compound. The main component of the crosslinking agent and the solvent is a Φ polymer cross-linking agent having a light absorbing property and a solvent. These antireflection film compositions may contain an acid component, an acid generator component, a liquid flow regulator, etc., if necessary. The light absorbing compound to be used may be a substance having high absorption energy for light in the wavelength range of the photosensitive characteristic of the photosensitive component in the photoresist provided on the antireflection film, such as a benzophenone compound or a benzotriene. An azole compound, an azo compound, a naphthalene compound, an anthraquinone compound, an anthraquinone compound, a triazine compound, or the like. Resins such as polyester, polyimine, polystyrene, novolac resin, polyacetal resin, acrylic resin, and the like. A resin having a light-absorbing group bonded by a chemical bond, for example, a resin having an anthracene ring, a naphthalene ring, a benzene ring, a quinoline ring, a quinoxaline ring, or a thiazole-31 - 200944944 ring light-absorbing aromatic ring structure. The underlayer film formed of the film-forming composition of the present invention is further absorbing the light with respect to the wavelength ' of light used in the lithography etching step. At this time, it functions as a layer having an effect of preventing light from being reflected by the substrate, that is, an antireflection film. Further, the film of the present invention can be used as a layer for preventing interaction between the substrate and the photoresist, and a layer for preventing the photoresist material from being exposed to the semiconductor substrate by the material formed by exposure of the photoresist or the photoresist.

To remove the solvent for drying, it was placed on a hot plate and heated at 1 ° C for 1 minute to form a sacrificial film (film thickness 450-500 nm). These sacrificial films were immersed in propylene glycol monomethyl ether of a solvent for φ photoresist, and as a result, they were insoluble in the solvent, and it was confirmed that a photocured film was formed by photoreaction. Test for flattening rate and tackiness The solutions of the film-forming compositions obtained in Examples 1 to 8 were each coated with a hole (diameter: 0.30/zm, depth: 1.0/zrn, ie, aspect ratio 3.3) using a spin coater. And a coating film was formed on the ceria (Si 02 wafer) substrate of the hole (1.0/m in diameter, 1.0/zm in depth, ie, aspect ratio 1.0). The ruthenium substrate used is a substrate having an Iso (coarse) and Dense (dense) pattern as shown in Fig. 1.

The sacrificial films of Examples 1 to 8 have excellent fluidity particularly in the fine Dense hole pattern in which the film thickness is difficult to fix. Even if the number of holes per unit area (hole density) on the hole substrate is larger than the Iso portion, the solution in which the majority of the sacrificial film forming composition can smoothly flow in, and a certain film thickness is obtained, so it is inferred that it can be reduced. The film thickness difference between the 1so portion and the 〇61 portion is increased, and the flattening rate is increased. Further, the sacrificial film-independent Iso portion and the Dense portion of the first to eighth embodiments can be planarized. Test of dry etching rate A solution of the film-forming compositions obtained in Examples 1 to 8 was applied to a semiconductor substrate (矽 wafer) by a spin coater to form a sacrificial film. Using an ultra-high pressure mercury lamp (Ussio Electric Co., Ltd., type UIS-501 1MIKY 'output power 500 W), the film was irradiated for 2 minutes (exposure 660 mJ/cm2) at a full wavelength of 5.5 mW. In order to remove the solvent, it was dried at -39 to 200944944, and it was placed on a hot plate and heated at 130 ° C for 2 minutes to form a sacrificial film. The film thickness is 460 to 480 nm. Next, the RIE system ES401 manufactured by Seonti, Japan, was used to measure the dry uranium speed (reduction in film thickness per unit time) of these sacrificial films under conditions of CF4 as a dry etching gas. The results are shown in Table 3. The selectivity in the table refers to the dry uranium engraving speed of 1.00 when compared with the photoresist for KrF laser lithography (Shin-Etsu Chemical Co., Ltd. under the trade name SEPR43 0), relative to light.
