Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a wafer provided with a bump by which the bump can be manufactured easily and economically while freely adjusting its height. SOLUTION: First, a conductive protection layer is formed on a wafer, and a first resist layer is formed in a part other than a part where a bump is to be formed on the conductive protection layer. A Zn layer is formed on the part where the bump is to be formed on the conductive protection layer, an Ni layer is formed on the Zn layer, and then a sputtering layer is formed on both the first resist layer and the Ni layer. Furthermore, a second resist layer is formed on a part that is on the sputtering layer and corresponds to the upper part of the first resist layer, and a conductive metallic layer is formed on a part that is on the sputtering layer and corresponds to the upper part of the Ni layer. Then, the second resist layer is removed, and the sputtering layer in a part where no conductive metallic layer is formed is removed. COPYRIGHT: (C)2004,JPO

Abstract:
A conductive sheet (1) for a non-contact type IC card having a built-in antenna has an insulating base body (2). A conductive layer (3) is formed on both of the front surface and the rear surface of the insulating base body (2). The conductive layers on the both surfaces are electrically connected via a through hole or a via hole (5) opening through the insulating base body. The conductive layers are formed directly on the insulating base body and have identical configuration on the side wall of the through hole or inside of the via hole and on the front and the rear surface of the insulating base body. The conductive layers also constitute a circuit containing an antenna.
