Abstract: PURPOSE:To obtain a semiconductor having a superior durability and having no coalescence of Sn by a method wherein, when a lead terminal formed on a film and electrodes on an IC are heated and fixed by pressure by a heat tool, a metal foil is interposed between the that tool and the lead terminal to perform a bonding. CONSTITUTION:A Cu foil is patterned on a film tape 7 consisting of a polyimide and so on and a lead terminal 2 is formed. A metal is piled up on electrodes of an IC chip 3 and bumps 4 are formed. The chip 3 is set on a bonding stage 6 and after the bumps 4 of the IC and the lead terminal 2 are aligned to each other, a metal foil 1 is set on the upper surface of the terminal 2. Then, a heat tool 5 is made to descend to heat and to fix by pressure and the metal foil on the terminal 2 is removed after bonding. By the above way, a trouble that Sn on the surface of the lead terminal coalesces on the contact bonding surface of the heat tool is eliminated and a trouble concerning the abrasion of the heat tool is also eliminated as the metal foil exists between the heat tool and the lead terminal and the heat tool can be used almost semipermanently.

Abstract: PURPOSE:To make moisture, such as sweat, absorbed into the band and to eliminate an uncomfortable sticky feel by using a blank material, such as high- polymer material, having water absorbency in the part of the band where the band comes into contact with the human skin during carrying. CONSTITUTION:Cowhide is used for surface skins 7 of the band and the cowhide is likewise used for a core skin 8. Further, the member, such as high-polymer material, having water absorbency, is used for the surface 9 in contact with the human skin during carrying. The core skin 8 of the band and the member 9, such as high-polymer material, having the water absorbency are fixed by adhesion. Since the high-polymer material having the water absorbency is used for the part in contact with the human skin, there is no uncomfortable sticky feel in spite of sweating, etc. The surface skins 10, 11 consist of the cowhide. The surface skin 11 which comes into contact with the human skin is provided with many holes and the core skin 12 is constituted of the high-polymer material having the water absorbency. Since the surface skin 11 is provided with the many holes, the moisture, such as sweat, is absorbed through the holes provided in the surface skin 11 into the core skin 12 having the water absorbency. The uncomfortable sticky feel is thus eliminated.
