PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor device capable of ensuring sufficient adhesion of a wiring member and preventing separation of the wiring member until a barrier layer having a function of improving adhesion is formed. To do. (A1) A recess is formed in an insulating film formed on a semiconductor substrate. (A2) A first film made of Mn is formed by CVD so as to cover the inner surface of the recess and the upper surface of the insulating film. (A3) A conductive material containing Cu as a main component is deposited on the first film, and the concave portion is filled with the conductive material. (A4) The semiconductor substrate is annealed. [Selection] Figure 3-2 |
