Abstract:
A method of fabricating thin film integrated circuit (I.C.) features, comprising the steps of:depositing a thin film material on an I.C. substrate,patterning said thin film material to establish a desired pattern of thin film features on said I.C. substrate,depositing a protective layer on the patterned thin film material,opening contact areas to said substrate through said protective layer,depositing metal in said contact areas opened to said substrate to provide connections to devices formed on said substrate,sintering said metal,opening contact areas to said patterned thin film material through said protective layer,depositing conductive material on said protective layer and in said contact areas opened to said patterned thin film material, anddry etching excess conductive material to form a desired metallization pattern which contacts said patterned thin film material.
