Abstract:
1. A method of manufacturing a paper-like RFID tap, comprising: an RFID thread assembly process of forming an RFID thread, said RFID thread assembly process includes: a metal foil laminated film fabricating process of bonding a metal foil to one surface of a base member to form a metal foil laminated film; an antenna pattern forming process of patterning said metal foil in said metal foil laminated film fabricated in said metal foil laminated film fabricating process to form an antenna; a protecting material bonding process of bonding a protecting material around an RFID chip on said antenna, said protecting material having a thickness such that a height of an upper surface thereof becomes larger than that of said RFID chip when the RFID chip is bonded by bonding pumps to said antenna; and an RFID chip bonding process of bonding the bumps of said RFID chip to said antenna; and a paper making process of inlaying said RFID thread formed in said RFID thread assembly process in between a first paper layer and a second paper layer and conducting heating, pressurizing and dewatering with use of rolls and drying; wherein said protecting material has a C-shaped or doughnut-shaped surface.
