Abstract
Corresponding parts to a first path portion in a first signal transmission path to a first semiconductor chip are an interconnection member and a second path portion a second signal transmission path to a second semiconductor chip and are not formed on the first tape. An electric length of the second signal transmission path is allowed to be adjusted independently of the first tape, so that the electric length of the second signal transmission path can be easily made equal to or substantially equal to that of the first signal transmission path.
