ABSTRACT:
A semiconductor device, which uses a film carrier, comprises a semiconductor element with a plurality of terminals, a resin film with a first surface and a second surface, the film having a hole in which the semiconductor element is mounted, and a plurality of lead wires formed on the first surface of the resin film. Each lead wire has an inner lead, an intermediate lead and an outer lead. The inner lead is connected to a corresponding one of the terminals of the semiconductor element. The outer lead is connected to a corresponding external electrode. The intermediate lead is situated between the inner lead and the outer lead. At least said intermediate lead is formed on the first surface of the film. Each outer lead and that portion of the intermediate lead, which is close to the outer lead, is substantially on a level with the external electrode.
