Abstract:
A method for fabricating an electrode structure comprising the steps of:(a) depositing a first metal film of a first metal on a silicon-containing film containing silicon as a principal constituent; (b) depositing a second metal film of a nitride of a second metal on said first metal film; (c) depositing a metal film with a high melting point on said second metal film, whereby forming a multi-layer film of said silicon containing film, said first metal film, said second metal film and said metal film with a high melting point; (d) depositing an insulating film on said multi-layer film; and (e) after step (d), carrying out annealing on said multi-layer film at a temperature of 750Â° or more, wherein in the step (d), said first metal is nitrided to be changed into a nitride of said first metal by diffusing the nitrogen in said second metal film into said first metal film.
