Further, it is required that the cured film formed using the photosensitive composition hardly change in transmittance even after being subjected to the heat treatment. In particular, even when various color filters and the cured film are arranged adjacent to each other, it is desirable that the transmittance does not easily change after the heat treatment.
- the fact that the transmittance hardly changes after the heat treatment is referred to as being excellent in heat resistance.
- the present inventors evaluated the above characteristics using the photosensitive composition described in Patent Document 1, and could not satisfy both characteristics in a well-balanced manner.
- an object of the present invention is to provide a photosensitive composition which can form a pattern having excellent rectangularity in cross-sectional shape and can form a cured film having excellent heat resistance.
- Another object of the present invention is to provide an infrared light cut filter formed using a photosensitive composition and a solid-state imaging device including the infrared light cut filter.

- the metal oxide is an oxide containing at least one or more elements selected from the group consisting of Si, Ti, Zr, and Al.
- the ultraviolet absorber is a UV absorber having a mass reduction rate at 150 ° C.
- the photosensitive composition according to any one of (3).
- the polymerization inhibitor is at least two or more selected from the group consisting of a hindered phenol compound, a phenol compound other than the hindered phenol compound, a benzoquinone compound, and a hydroquinone compound.
- the polymerization inhibitor is one or more first polymerization inhibitors selected from the group consisting of a hindered phenol compound, a benzoquinone compound, and a hydroquinone compound, and a phenol compound other than the hindered phenol compound.
- the photosensitive composition according to (7) comprising a compound.
- the photosensitive composition according to (8) wherein the mass ratio of the content of the phenolic compound other than the hindered phenolic compound to the total content of the first polymerization inhibitor is 0.0009 to 0.17. object.
- (12) A solid-state imaging device including the infrared light cut filter according to (11).
- the photosensitive composition which can form the pattern excellent in the rectangular shape of a cross-sectional shape and can form the cured film excellent in heat resistance can be provided. Further, according to the present invention, an infrared cut filter formed using the photosensitive composition and a solid-state imaging device including the infrared cut filter can be provided.
- FIG. 1 is a schematic sectional view illustrating a configuration of an embodiment of a solid-state imaging device of the present invention.
- FIG. 2 is a functional block diagram of an imaging device to which the solid-state imaging device of the present invention is applied. It is a figure for explaining pattern rectangularity evaluation.
- the notation not indicating substituted or unsubstituted includes not only a group having no substituent but also a group having a substituent.
- the “alkyl group” includes not only an alkyl group having no substituent (unsubstituted alkyl group) but also an alkyl group having a substituent (substituted alkyl group).
- “to” is used to mean that the numerical values described before and after it are included as the lower limit and the upper limit.
- (meth) acrylate represents acrylate and methacrylate
- (meth) acryl represents acryl and methacryl
- (meth) acryloyl represents acryloyl and methacryloyl.
- “monomer” and “monomer” have the same meaning. Monomers are compounds distinguished from oligomers and polymers and have a weight average molecular weight of 2,000 or less.
- a polymerizable compound refers to a compound having a polymerizable functional group, and may be a monomer or a polymer.
- the polymerizable functional group refers to a group that participates in a polymerization reaction.
- the total solid content refers to the total mass of components excluding the solvent from the total composition of the composition.
- the solid content in the present invention is a solid content at 25 ° C.
- the feature of the present invention is that the mass ratio between the ultraviolet absorber and the polymerization inhibitor is adjusted. It has been found that by adjusting the mass ratio to a predetermined range, heat resistance and pattern rectangularity (rectangularity of a pattern to be formed) can be achieved in a better balance.
- the photosensitive composition contains metal-containing tungsten oxide particles, a polymerizable compound, a polymerization initiator, an ultraviolet absorber, and a polymerization inhibitor.
- a photosensitive composition also simply referred to as “composition”.
- the metal-containing tungsten oxide particles are tungsten oxide particles containing metal atoms.
- the specific particles have an effect as an infrared absorber because they selectively block infrared light (light having a wavelength of about 800 to 1200 nm) depending on the crystal structure. Therefore, the infrared light cut filter including the specific particles has a high light-shielding property in an infrared region and a high light-transmitting property in a visible light region.
- the specific particles have a small absorption of light having a shorter wavelength than the visible region used for exposure, such as a high-pressure mercury lamp, KrF, and ArF used for image formation. Therefore, as described later, the photosensitive composition of the present invention has excellent pattern formability, and can finely control the shape of the infrared light cut filter.
- the type of the metal atom contained in the specific particles is not particularly limited, but an alkali metal may be mentioned in that it is more excellent in shielding infrared light.
- the specific particles are preferably represented by the following general formula (composition formula) (I).
- Composition formula) (I) M x W y O z (I) M represents an alkali metal, W represents tungsten, and O represents oxygen. 0.001 ⁇ x / y ⁇ 1.1 2.2 ⁇ z / y ⁇ 3.0
- the alkali metal of M may be one kind or two or more kinds.
- Rb or Cs is preferable, and Cs is more preferable.
- x / y is 0.001 or more, infrared light can be sufficiently shielded, and when x / y is 1.1 or less, generation of an impurity phase in specific particles can be further avoided.
- z / y is 2.2 or more, chemical stability as a material can be further improved, and when it is 3.0 or less, infrared light can be further shielded.
- Specific examples of the specific particles containing an alkali metal represented by the general formula (I) include Cs 0.33 WO 3 , Rb 0.33 WO 3 , K 0.33 WO 3, and the like. Cs 0.33 WO 3 or Rb 0.33 WO 3 is preferable, and Cs 0.33 WO 3 is more preferable.
- the surface of the metal-containing tungsten oxide particles is preferably coated with a metal oxide in that the effect of the present invention is more excellent.

Abstract
L'invention concerne : une composition photosensible qui permet de former un motif qui est excellent en termes de rectitude d'une forme de section transversale et qui permet de former un film durci ayant une excellente résistance à la chaleur ; un filtre coupant la lumière infrarouge ; et un dispositif d'imagerie à semi-conducteurs. Cette composition photosensible contient des particules d'oxyde de tungstène qui contiennent du métal, un composé polymérisable, un initiateur de polymérisation, un absorbeur de rayonnement ultraviolet et un inhibiteur de polymérisation. Le rapport en poids de la teneur en absorbeur de rayonnement ultraviolet à la teneur en inhibiteur de polymérisation est de 0,08 à 330.
