Abstract

PURPOSE:To increase the strength of a flange part as compared with a base material alone and to enhance the bonding strength of a card and a module, and that of a substrate and a sealing resin, by using a copper clad laminated sheet in the flange part of the module of a thin semiconductor card. CONSTITUTION:A semiconductor card module 3 is formed into a card by positioning an electrode 4 to the back surface of a resin seal parts 5 and providing the resin seal part in a card 2. The base material 6 of a flange part 8 is a copper clad plate and an uneven part is provided thereto by etching the copper foil 7 on the base material. By this method, the bonding strength of the card main body 2 and the flange part 8 of the semiconductor module 3 is especially increased and strength enhancing effect is also obtained.
