Abstract
Abstract A TAB film tape carrier (1) used for making semiconductor devices is described. This TAB film tape carrier comporises a substrate (2), and copper foil wiring (3a) on the substrate and having a predetermined lead form patterned by laminating and etching, the copper foil wiring being made of rolling copper recrystallized by annealing treatment.
