METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE AND SEMICONDUCTOR DEVICE MANUFACTURING APPARATUS

摘要

A method of manufacturing a semiconductor device includes: forming a first conductive film on a substrate; forming an insulating film to cover the conductive film; etching the insulating film to form an opening portion to expose at least a portion of the first conductive film in the insulating film; irradiating the opening portion with ultraviolet rays in a reduction gas atmosphere; forming a barrier metal film in the opening portion; and forming a second conductive film on the barrier metal film.
