    • A structure for resistors and the method for tuning the same. The resistor comprises an electrically conducting region coupled to a liner region. Both the electrically conducting region and the liner region are electrically coupled to first and second contact regions. A voltage difference is applied between the first and second contact regions. As a result, a current flows between the first and second contact regions in the electrically conducting region. The voltage difference and the materials of the electrically conducting region and the liner region are such that electromigration occurs only in the electrically conducting region. As a result, a void region within the electrically conducting region expands in the direction of the flow of the charged particles constituting the current. Because the resistor loses a conducting portion of the electrically conducting region to the void region, the resistance of the resistor is increased (i.e., tuned).
    • 电阻器结构及其调谐方法。 电阻器包括耦合到衬垫区域的导电区域。 导电区域和衬里区域都电耦合到第一和第二接触区域。 在第一和第二接触区域之间施加电压差。 结果,电流在导电区域中的第一和第二接触区域之间流动。 导电区域和衬垫区域的电压差和材料使得电迁移仅在导电区域中发生。 结果,导电区域内的空隙区域在构成电流的带电粒子的流动方向上膨胀。 因为电阻器将导电区域的导电部分损失到空隙区域,电阻器的电阻增加(即调谐)。
