Abstract

PURPOSE:To improve an adhesive power, by a method wherein a part, where an electrode is adhered to outer leads of a tape carreir of a conductor at a drive side, or either of the outer leads is made of tin, and the other is made of a metal having an excellent hot press adhesives. CONSTITUTION:A nichrome film 9 is laminated on a nitrided tantalum film 8 on a ceramic substrate 1, and an electrode 11, whereon a gold film 10 is laminated, is further formed thereon. A tape carrier 5, connecting the electrode 11 to a conductor path 6 at a power source side on a glass epoxy substrate 3, is formed such that an IC chip 4 is placed in an opening 13 of a polyimide film 12, and an inner lead 14a of a steel-made conductor path 14 is adhered to a gold bump 15 of the IC chip 4. An outer lead 14b of the conductor path 14b is covered by silver plating. The adhesion of the electrode 11 of the outer lead 14b to the conductor path 6 at the power source side is such that, since the outer lead 14b is made of tin and the electrode and the conductor path 6 at the power source side are made of gold, tin is thermally adhered by pressing to gold, and this improves an adhesive power.
