An etch stop layer(49a) is formed on the resultant structure. After forming a contact in the etch stop layer(49a), the second interlayer dielectric(51) is formed on the resultant structure. A metal interconnection hole(53) is formed to expose the contact by selectively etching the second interlayer dielectric. A metal interconnection barrier layer(55) and tungsten film(57) are formed in the metal interconnection hole(53).
