Abstract

PURPOSE:To protect a lower metal interconnection against a thermal shock by a method wherein a high melting metal film is formed on the lower metal interconnection. CONSTITUTION:An interlaminar insulating film 12 is formed on a semiconductor substrate 11. Next, an Al interconnection 13 is formed on the film 12. Then, a high melting metal film 14 is formed so as to prevent the interconnection 13 from being heated it high temperature. An interlaminar insulating film 15 is formed on the film 14. An Al interconnection 16 is built on the film 15. A high melting metal film 17 is formed on the interconnection 16 to prevent it from being heated at a high temperature. The semiconductor provided with a multilayer interconnection is formed in the processes as mentioned above. By these processes, a lower Al interconnection can be protected against a thermal shock. And a sputtering method performed at a high temperature can be applied, so that a multilayer interconnection used for a power source or the like of a semiconductor device high in integration and density and large in scale can be formed into a required shape.
