ELECTROLYTIC COPPER FOIL WITH CARRIER FOIL AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide the electrolytic copper foil with carrier foil and using an organic agent in the joining-interface layer with the lower-limit peel strength between the carrier foil and electrolytic copper foil controllable and its manufacturing method. SOLUTION: This electrolytic copper foil with carrier foil is manufactured by forming a joinig-interface layer on the carrier foil surface and forming an electrolytic copper foil layer on the joining-interface layer. In this case, copper foil is used as the carrier foil, and a mixture of the organic agent and metallic particles is used in the joining-interface layer.
