摘要： It is an object of the present invention to provide a method for producing gold colloid having a targeted particle size, a sharp particle size distribution and a uniform and perfect spherical shape. The present invention relates to a method for producing gold colloid including a nucleation step of forming nuclear colloidal particles by adding a first reducing agent to a first gold salt solution; and a growth step of growing nuclear colloid by adding a second gold salt and a second reducing agent to the solution of the nuclear colloidal particles, characterized in that the growth step is performed at least once; a citrate is used as the first reducing agent and an ascorbate is used as the second reducing agent; and the addition of the ascorbate in the growth step is performed simultaneously with addition of the second gold salt. According to the method for producing gold colloid of the present invention, gold colloid having a sharp particle size distribution and a uniform and perfect spherical shape can be obtained.

摘要： An object of the present invention is to provide a purification method to give dodecacarbonyl triruthenium (DCR) which serves as a raw material for chemical vapor deposition and does not cause the contamination of a thin film with impurities even when used to form a ruthenium thin film. The present invention relates to a method in which the dissolved oxygen concentration in the solvent is made 0.2 mg/L or less in at least a dissolution stage, and an organic ruthenium compound including DCR as a raw material for chemical vapor deposition is purified by a recrystallization method. The present invention allows a trace amount of impurities to be separated from DCR. When a ruthenium thin film is formed by use of DCR thus obtained, the formed film is hardly contaminated with impurities. Additionally, the purification method of the present invention is also applicable for recovering/purifying DCR after being used for the formation of a ruthenium thin film.

摘要： The present invention is an organoruthenium compound for a chemical vapor deposition raw material, including dodecacarbonyl triruthenium represented by the following chemical formula, wherein the iron (Fe) concentration is 1 ppm or less. The DCR in the present invention can be produced by obtaining crude DCR by directly carbonylating ruthenium through allowing a ruthenium salt and carbon monoxide to react with each other and by purifying the crude DCR by a sublimation method. In the synthesis step, the concentration of Fe in the obtained crude DCR is preferably set at 10 ppm or less.
