    • A chip sized semiconductor device (30) includes a semiconductor chip (32) having upper and lower surfaces. The chip (32) has electrodes (36) formed on its upper surface. An electrically insulating passivation film (34) is formed on the upper surface of the semiconductor chip (32) except for areas where the electrodes (36) exist. An anisotropic conductive sheet (38) has an upper surface provided with a circuit pattern (40) formed on it and a second surface adhered to the passivation film (34). The circuit pattern (40) has inner and outer connecting portions. An electrically insulating film (42) covers the upper surface of the anisotropic conductive sheet (38) so that the outer connecting portions of the circuit pattern (40) are exposed to be connected to external connecting terminals (46). The anisotropic conductive sheet (38) is partially pressed at positions corresponding to the electrodes (36), so that the inner portions of the circuit pattern (40) are thereby electrically connected to said electrodes (36) of the semiconductor chip (32).
    • 芯片尺寸的半导体器件(30)包括具有上表面和下表面的半导体芯片(32)。 芯片(32)具有形成在其上表面上的电极(36)。 除了存在电极(36)的区域之外,在半导体芯片(32)的上表面上形成电绝缘钝化膜(34)。 各向异性导电片(38)具有设置有形成在其上的电路图案(40)的上表面和粘附到钝化膜(34)的第二表面。 电路图案(40)具有内部和外部连接部分。 电绝缘膜(42)覆盖各向异性导电片(38)的上表面,使得电路图案(40)的外部连接部分暴露以连接到外部连接端子(46)。 各向异性导电片(38)被部分地压在与电极(36)对应的位置处,使得电路图案(40)的内部部分电连接到半导体芯片(32)的所述电极(36)。
