    • An integration approach to improve electromigration resistance in a semiconductor device is described. A via hole is formed in a stack that includes an upper dielectric layer, a middle TiN ARC, and a lower first metal layer and is filled with a conformal diffusion barrier layer and a second metal layer. A key feature is that the etch process can be selected to vary the shape and location of the via bottom. A round or partially rounded bottom is formed in the first metal layer to reduce mechanical stress near the diffusion barrier layer. On the other hand, a flat bottom which stops on or in the TiN ARC is selected when exposure of the first metal layer to subsequent processing steps is a primary concern. Electromigration resistance is found to be lower than for a via structure with a flat bottom formed in a first metal layer.
    • 描述了一种用于提高半导体器件中的电迁移阻力的集成方法。 在包括上电介质层,中间TiN ARC和下第一金属层的堆叠中形成通孔,并且填充有共形扩散阻挡层和第二金属层。 一个关键特征是可以选择蚀刻工艺来改变通孔底部的形状和位置。 在第一金属层中形成圆形或部分圆形的底部,以减小扩散阻挡层附近的机械应力。 另一方面,当第一金属层暴露于后续处理步骤时,选择在TiN ARC上或其中停止的平底,这是首要考虑的问题。 发现耐电迁移性低于在第一金属层中形成的平坦底部的通孔结构。
