    Abstract: PURPOSE:To obtain adherent insulating tape having excellent characteristics in adhesion bond between metal conductor, semiconductor and the like, reliability and mass-productivity by a method wherein thermoplastic polymer, which is formed on insulating board, has specified polyimide as essential ingredient and specified glass transition temperature and modulus of elasticity. CONSTITUTION:On both the sides or one side of insulating board, thermoplastic polymer layer, the essential ingredient of which is represented by the formula I. In this case, the glass transition temperature of the thermoplastic polymer is 180-280 deg.C and its modulus of elasticity is 10 -10 dyne/cm at 25 deg.C 10 -10 dyne/ cm at 250-300 deg.C. Silane coupling agent may be reacted or mixed with the thermoplastic polyimide at or after the synthesization of the thermoplastic polyimide. The adherent insulating tape 4 has excellent bonding characteristics to IC chip 1 and the like and adhesion takes place in a short period of time.

    Abstract: PURPOSE:To obtain a double-sided FMCL having high bonding strength among layers by bringing two layers brought into contact with the metallic foil layer of a heat-resistant polymer layer to the state of thermocompression bonding with the metallic foil layer and symmetrizing the heat-resistant polymer layer in the thickness direction to the central surface of the heat-resistant polymer layer. CONSTITUTION:A flexible metallic-foil laminate(FMCL) in which heat-resistant polymer layers are formed between two layers of metallic foil layers is manufactured, the heat-resistant polymer layers are composed of three layers or more, two layers brought into contact with the metallic foil layers can be thermocompression bonded with the metallic foil layers, and the heat-resistant polymer layers are symmetrized in the thickness direction to the central surfaces of the heat-resistant polymer layers. Three layers or more of the heat-resistant polymer layers are shaped through coating in the double-sided FMCL having three layers or more of the heat-resistant polymer layers at that time, thus acquiring high bonding strength through mixing and/or crosslinking near the interfaces of the polymer layers.

    Abstract: PURPOSE:To reduce the curling of the heat-resistant polymer film remaining by removing a metal foil by lowering the amount of the residual solvent present in the heat-resistant polymer film. CONSTITUTION:The heat-resistant polymer film layer of a flexible metal foil laminated sheet is composed of a heat-resistant polymer containing an imide bond and/or having a heterocyclic ring other than the imide bond. This heat- resistant polymer is applied to a metal foil in a state dissolved in a solvent or in such a state that the precursor of the heat-resistant polymer is dissolved in a solvent and the coating layer is dried under heating using hot nitrogen, far infrared rays or high frequency waves to perform the removal of the solvent and/or dehydration. At this time, it is necessary to control the residual amount of the solvent to at least 0.02% or less and, by gradually raising temp. from room temp. at the time of heating, the solvent is prevented from remaining in the vicinity of the metal foil of the heat-resistant polymer.
