  • Patent number: 6909173
    Abstract: The invention concerns a flexible substrate comprising an inner lead connected to an external connection terminal formed on a substrate, and a base film formed on the lead. The base film area above the substrate and closest to the terminal is thinner than the terminal. The invention also provides a semiconductor device comprising an inner lead connected to an external connection terminal formed on a substrate, and a base film formed on the lead. The base film area above the substrate and closest to the terminal is thinner than the terminal. The invention also provides for a manufacturing method a semiconductor device comprising a substrate, an external connection terminal, and an inner lead with a base film. Further, the invention provides a semiconductor device with a substrate with a chamfered corner between the connection and side faces. By the invention, connection of an inner lead or a flexible substrate is made easier.
