Abstract: Disclosed herein is an electronic component that includes a substrate, a planarizing layer covering a surface of the substrate, a first conductive layer formed on the planarizing layer and having a lower electrode, a dielectric film made of a material different from that of the planarizing layer and covering the planarizing layer and first conductive layer, an upper electrode laminated on the lower electrode through the dielectric film, and a first insulating layer covering the first conductive layer, dielectric film, and upper electrode. An outer periphery of the first insulating layer directly contacts the planarizing layer without an intervention of the dielectric film.

Abstract: Generation of by-product is reduced by producing a triazolylmethyl cycloalkanol derivative by reacting a cycloalkanone derivative and an alkali metal salt of 1,2,4-triazole in the presence of a sulfur ylide at a reaction temperature of higher than 110° C. and 140° C. or lower.

Abstract: The present invention relates to a method of producing trimethylsulfoxonium bromide by reacting dimethyl sulfoxide with methyl bromide (MeBr), wherein MeBr is added in a manner that satisfies conditions (1) and (2): (1) MeBr is added at an addition rate that complies with a predetermined feeding profile, (2) MeBr is added upon the temperature in the reaction system reaching a predetermined maximum temperature.
