SEMICONDUCTOR-DEVICE MANUFACTURING METHOD, STORAGE MEDIUM, AND SEMICONDUCTOR DEVICE

摘要

A semiconductor device manufacturing method includes forming a second conductive layer on an underlying layer which has an insulating layer in which a recess is formed and a first conductive layer exposed on a bottom surface of the recess; forming a third conductive layer on the second conductive layer; supplying, into the third conductive layer, a material solid-soluble in the third conductive layer; and heating the third conductive layer into which the solid-soluble material is supplied.
