Abstract: There are provided a carbon dioxide storage apparatus and a carbon dioxide storage method which, through direct injection of carbon dioxide into an underground brine aquifer, can store carbon dioxide efficiently in the brine aquifer. A filter formed of, for example, grindstone is provided at a tip portion of an injection well. A pumping apparatus pumps carbon dioxide stored in a carbon dioxide tank. The pumping apparatus feeds carbon dioxide from the carbon dioxide tank into the injection well by means of a pump. In the pumping apparatus, carbon dioxide is held within a predetermined pressure range and a predetermined temperature range. Carbon dioxide is fed through the injection well, and is injected into a brine aquifer. Carbon dioxide injected into the brine aquifer assumes the form of microbubbles.

Abstract: A coating fluid comprising a boron compound, an organic binder, a silicon compound, an alumina precursor, and water and/or an organic solvent is used to diffuse boron into a silicon substrate to form a p-type diffusion layer. The coating fluid is spin coated onto the substrate to form a uniform coating having a sufficient amount of impurity whereupon a p-type diffusion layer having in-plane uniformity is formed.

Abstract: Disclosed is a phosphorus paste for diffusion that is used in continuous printing of a phosphorus paste for diffusion on a substrate by screen printing. The phosphorus paste for diffusion does not undergo a significant influence of ambient humidity on viscosity and has no possibility of thickening even after a large number of times of continuous printing. The phosphorus paste for diffusion is coated on a substrate by screen printing for diffusion layer formation on the substrate. The phosphorus paste for diffusion includes a doping agent containing phosphorus as a dopant for the diffusion layer, a thixotropic agent containing an organic binder and a solid matter, and an organic solvent. The doping agent is an organic phosphorus compound.
