    摘要: A semiconductor substrate cleaning liquid composition is provided that includes one or more types selected from the group consisting of a compound having at least two sulfonic acid groups per molecule, phytic acid, and a condensed phosphoric acid compound; an inorganic acid; and water. There is also provided a process for cleaning a semiconductor substrate that includes a first step of cleaning the semiconductor substrate using the semiconductor substrate cleaning liquid composition and, subsequent to the first step, a second step of cleaning the semiconductor substrate with pure water, ozone water formed by dissolving ozone gas in pure water, or aqueous hydrogen peroxide.

    摘要: A method has been disclosed which cleans a semiconductor substrate using a cleaning liquid produced by mixing bubbles of a gas into an acid solution in which the gas has been dissolved to the saturated concentration and which brings the zeta potentials of the semiconductor substrate and adsorbed particles into the negative region by the introduction of an interfacial active agent. Alternatively, a semiconductor substrate is cleaned using a cleaning liquid produced by mixing bubbles of a gas into an alkaline solution in which the gas has been dissolved to the saturated concentration and whose pH is 9 or more.
