    • A transmission cable includes multiple signal lines formed on one side of an insulation layer and a ground line between the signal lines. The ground line is electrically connected to a shield layer formed on a back surface side of the insulation layer and to a noise suppressing layer having a high electric resistance value than the shield layer via a metal bump embedded and formed in the insulation layer. The noise suppressing layer has a function to suppress an unwanted emission and/or a noise and has a function as an etching barrier layer serving as an etching stopper in a step for forming the metal bump. Thus, the transmission cable can suppress an increase of an electric resistance and a connection resistance between the ground line and the shield layer.
    • 传输电缆包括形成在绝缘层的一侧上的多个信号线和信号线之间的接地线。 接地线通过嵌入并形成在绝缘层中的金属凸块电连接到形成在绝缘层的背面侧上的屏蔽层和与屏蔽层相比具有高电阻值的噪声抑制层。 噪声抑制层具有抑制不需要的发射和/或噪声的功能,并且在用于形成金属凸块的步骤中具有用作蚀刻停止层的蚀刻阻挡层的功能。 因此,传输电缆可以抑制接地线和屏蔽层之间的电阻和连接电阻的增加。

    • A transmission cable is provided and includes multiple signal lines formed on one side of an insulation layer 1 and a ground line between the signal lines. The ground line is electrically connected to a shield layer formed on a back surface side of the insulation layer and to a noise suppressing layer having a high electric resistance value than the shield layer via a metal bump embedded and formed in the insulation layer. The noise suppressing layer has a function to suppress an unwanted emission and/or a noise and has a function as an etching barrier layer serving as an etching stopper in a step for forming the metal bump. Thus, the transmission cable can simplify a manufacturing process and reduce a manufacturing cost, and can suppress an increase of an electric resistance and a connection resistance between the ground line and the shield layer, thus capable of providing the transmission cable capable of fast transfer and large-capacity transfer with high reliability.
    • 提供传输电缆,并且包括形成在绝缘层1的一侧上的多个信号线和信号线之间的接地线。 接地线通过嵌入并形成在绝缘层中的金属凸块电连接到形成在绝缘层的背面侧上的屏蔽层和与屏蔽层相比具有高电阻值的噪声抑制层。 噪声抑制层具有抑制不需要的发射和/或噪声的功能,并且在用于形成金属凸块的步骤中具有用作蚀刻停止层的蚀刻阻挡层的功能。 因此,传输电缆可以简化制造工艺并降低制造成本,并且可以抑制接地线和屏蔽层之间的电阻和连接电阻的增加,从而能够提供能够快速传输的传输电缆, 大容量传输具有高可靠性。
