    摘要: A semiconductor device and fabrication method thereof. The semiconductor device comprises a substrate, an electroactive organic layer with conformal step coverage and uniform thickness, and a metal layer. The substrate is a conductive substrate or a nonconductive substrate with a conductive layer formed thereon. The electroactive organic layer and the metal layer are formed sequentially on the conductive substrate or the conductive layer, wherein the electroactive organic layer comprises metal atoms and serves as a seed layer, resulting in the metal layer formed in-situ.

    摘要: A new method of metallization using a three-dimensional aluminum reservoir to increase the electromigration lifetime of a tungsten plug in the fabrication of integrated circuits is achieved. An insulating layer is provided covering semiconductor device structures in and on a semiconductor substrate. Aluminum lines are formed over the insulating layer. An intermetal dielectric layer is deposited overlying the aluminum lines. Via openings are made through the intermetal dielectric layer to the aluminum lines. Aluminum is selectively deposited into the via openings to form aluminum reservoirs in the bottom of the via openings wherein the aluminum does not completely fill the via openings. Tungsten plugs are formed within the via openings overlying the aluminum reservoirs wherein the aluminum reservoirs provide a source for electrons to replenish electrons lost through electromigration to complete formation of tungsten plug metallization with increased electromigration lifetime in the fabrication of integrated circuits.
