Abstract:
A method of fabricating a semiconductor device comprising steps of:forming an interlayer dielectric film having an opening; forming a first conductive member, which consists of a single layer, in said opening by sputtering; and performing first heat treatment at a temperature capable of reducing the quantity of moisture and hydroxyl groups in said interlayer dielectric film in advance of formation of said first conductive member, wherein said step of forming said first conductive member includes a step of performing said sputtering at a low temperature and thereafter performing said sputtering at a high temperature thereby forming said first conductive member; the method further comprising a step of forming a second conductive member containing titanium in said opening after performing said first heat treatment in advance of formation of said first conductive member, wherein the second conductive member is formed at a temperature substantially not at a level capable of removing moisture and hydroxyl groups from the interlayer dielectric film.
