    • There is a method of manufacturing an RFID, in which a semiconductor chip with a memory is bonded to an antenna, so that the information recorded in the memory can be transmitted through the antenna. In the RFID, a PET film, a PEN film, or a sheet of paper is used as the base material of the antenna. The method includes: aligning the semiconductor chip with gold bumps relative to the antenna, in which a metal foil formed of an aluminum or an aluminum alloy is adhered to the base material, including a polyethylene terephthalate or a polyethylene naphthalate; pressing the semiconductor chip to the antenna; and applying ultrasonic waves under an ambient temperature lower than the glass transition temperature of the polyethylene terephthalate or the polyethylene naphthalate, to thereby bond the gold bumps and the metal foil. Thus, the method suppresses the deformation of the antenna.
    • 存在制造RFID的方法,其中具有存储器的半导体芯片被结合到天线,使得可以通过天线发送记录在存储器中的信息。 在RFID中,使用PET膜,PEN膜或纸张作为天线的基材。 该方法包括:将半导体芯片与相对于天线的金凸块对准,其中由铝或铝合金形成的金属箔粘附到包括聚对苯二甲酸乙二醇酯或聚萘二甲酸乙二醇酯的基材上; 将半导体芯片按压到天线; 并在低于聚对苯二甲酸乙二醇酯或聚萘二甲酸乙二醇酯的玻璃化转变温度的环境温度下施加超声波,从而结合金凸块和金属箔。 因此,该方法抑制天线的变形。
