摘要： PROBLEM TO BE SOLVED: To provide a packing tape body which is easy to pack and unpack and can be recycled. SOLUTION: A packing tape body 10 is provided with carrier tape 11 in which QFP.IC storage cavities 14 are arranged longitudinally, and lids 12 for covering the openings of the cavities 14. On female hinges 19 formed at the right and left sides of the opening of each cavity 14, male hinges 23 formed at the outside ends of the right and left rids 12 are supported so as to be freely turnable, and the right and left lids 12 are integrated with the carrier tape 11 so as to open/close the opening of the corresponding cavity freely. The male hinge 23 of each lid 12 is provided with a stopper 25 which engages with the stopper 26 of the corresponding female hinge 19 when the opening of the corresponding cavity is closed. Thus, when the lids 12, which are free to be opened/ closed, is opened, a QFP.IC 1 is freely taken out of the cavity 14 and inserted into it, therefore this facilitates packing and unpacking. Because damage and the like are not caused to the carrier tape 11 and lids 12 after unpacking, the packing tape body 10 can be recycled.

摘要： PURPOSE: To provide a semiconductor device mounting technology which elevates the packing density and facilitates the mounting, while avoiding increasing the mounting area. CONSTITUTION: A composite semiconductor device 2 is composed of two semiconductor devices SLP.IC 20 and QFP.IC 10 laminated one above the other, each having a single line package having outer leads 22 extruding from one side face of a resin seal 21. The device 2 is mounted on a mounting substrate 30 electrically and mechanically connected thereto to form a mounted structure 1. Since the two semiconductor devices are laminated, the mounting area is small, whereas they are mounted at a high packing density. Since the outer leads of the upper SLP.IC have a single line type structure, the relative position to the lower QFP.IC can be selected freely to facilitate mounting.
