SEMICONDUCTOR DEVICE, AND METHOD AND APPARATUS FOR MANUFACTURING SAME

摘要

For the purpose of removing an oxide film on the surface of a varying metal electroconductive material used for wiring in a semiconductor device without inflicting damage on a peripheral structure, the oxide film formed on the surface of a metal electroconductive region 12 is subjected to a reducing treatment that is effected by placing the metal electroconductive region 12 in a reducing treatment chamber 22, causing an oxygen pump 30 to introduce into the reducing treatment chamber 22 an inert gas having at least an oxygen partial pressure thereof suppressed to 1x10-13 atmosphere or less and heating the metal electroconductive region 12 with a heating device 25.
