摘要:
An imaging photodetection device (4) includes: a plurality of photodetectors (6) that are arrayed on a substrate (5) at least along a first direction; a transparent low refractive index layer (12) that is formed above the plurality of photodetectors; and a plurality of transparent high refractive index sections (13) that are embedded in the transparent low refractive index layer along the first direction. On a cross-section of the transparent high refractive index sections orthogonal to the substrate and along the first direction, central axes (14) of the transparent high refractive index sections are bent stepwise. Light that enters the transparent low refractive index layer and the transparent high refractive index section passes therethrough to be separated into 0th-order diffracted light, 1st-order diffracted light, and −1st-order diffracted light. Thereby, improvement in the efficiency of light utilization and pixel densification can be realized.

An LED module comprises: an LED element having an electrode for flip chip mounting; a wiring board having at least two metal layers and an electrically insulating layer including a polymer resin and being interposed between each two of the metal layers; and a metal film layer of the LED element for conducting heat from the LED element. A first metal layer of the at least two metal layers has a power supply metal pattern and a heat transfer metal pattern that are formed electrically insulated from each other. The power supply metal pattern and the electrode are connected to each other; the heat transfer metal pattern and the metal film layer are connected through an electrically insulating portion interposed therebetween; and the heat transfer metal pattern and the metal layers other than the first metal layer are coupled to each other through a heat transfer portion.

A diffractive optical element that can maintain transparency and be molded easily, and a method for manufacturing the same are provided.A diffractive optical element (10) includes a substrate (11), a protective film (13a, 13b), and a diffraction grating (12a, 12b) disposed between the substrate (11) and the protective film (13a, 13b), wherein the diffraction grating (12a, 12b) is formed of a composite material containing a resin and inorganic particles, a volume ratio of the inorganic particles with respect to the composite material is equal to or smaller than 50% by volume, and the diffraction grating (12a, 12b) has a thickness of equal to or smaller than 20 μm. Since the diffractive optical element (10) uses the composite material containing the resin and the inorganic particles as a material for the diffraction grating (12a, 12b), which is relatively difficult to process, the moldability improves compared with the conventional case of using glass, etc.

A radiation-sensitive resin composition comprising (A) a photoacid generator such as 2,4,6-trimethylphenyldiphenylsulfonium 2,4-difluorobenzenesulfonate or 2,4,6-trimethylphenyldiphenylsulfonium 4-trifluoromethylbenzenesulfonate and (B) a resin having an acetal structure typified by a poly(p-hydroxystyrene) resin in which a part of hydrogen atoms of phenolic hydroxyl groups have been replaced by 1-ethoxyethyl groups, 1-ethoxyethyl groups and t-butoxycarbonyl groups, or 1-ethoxyethyl groups and t-butyl groups. The resin composition is sensitive to deep ultraviolet rays and charged particles such as electron beams, exhibits excellent resolution performance and pattern shape-forming capability, and suppresses a nano-edge roughness phenomenon to a minimal extent.
摘要:
A polyurethane foam is constituted by using a blowing agent selected from the group consisting of iodofluorohydrocarbons, perfluoroalkenes and hydrogen-containing fluoromorpholine derivatives. These blowing agents have a low thermal conductivity and a short life in the air, and thus impose no or very small load such as ozone layer depletion potential (ODP) and global warming potential (GWP) on the environment. The iodofluorohydrocarbon, in particular, can give an incombustibility and self-extinguishing property to the conventionally used inflammable substance such as cyclopentane or the like, and thus is also advantageous from the viewpoint of safety of the thermal insulating material.

摘要:
A surface of a transparent substrate 5 which is adjacent to a light emitting body has a surface structure 13 that is defined by dividing the surface into a plurality of linear segments of width w which are inclined so as to extend in a specific direction in a plane of the surface and dividing the linear segments into minute regions aligned along the longitudinal direction of the linear segments such that the largest inscribed circle of the minute regions has a diameter from 0.2 μm to 1.5 μm. Each of the minute regions is formed by a raised or recessed portion formed in the surface of the transparent substrate 5. The proportion of the raised portions and the proportion of the recessed portions, P and 1−P, are determined such that P is in the range of 0.4 to 0.98.
