    摘要: A method for forming an interconnect structure includes forming a recess in a dielectric layer of a substrate. An adhesion barrier layer is formed to line the recess. A first stress level is present across a first interface between the adhesion barrier layer and the dielectric layer. A stress-reducing barrier layer is formed over the adhesion barrier layer. The stress-reducing barrier layer reduces the first stress level to provide a second stress level, less than the first stress level, across a second interface between the adhesion barrier layer, the stress-reducing barrier layer, and the dielectric layer. The recess is filled with a fill layer.

    摘要: A method for forming an interconnect structure includes forming a recess in a dielectric layer of a substrate, forming a first transition metal layer in the recess on corner portions of the recess, and forming a second transition metal layer in the recess over the first transition metal layer to line the recess. The method further includes filling the recess with a fill layer and annealing the substrate so that the first transition metal layer and the second transition metal layer form an alloy portion proximate the corner portions during the annealing, the alloy portion having a reduced wettability for a material of the fill layer than the second transition metal. Additionally, the method includes polishing the substrate to remove portions of the fill layer extending above the recess.

    摘要: A method for accurately and objectively evaluating stress migration effects on long term reliability of integrated circuits. A sample containing a conductive runner is fabricated according to a given fabrication process. The fabricated sample undergoes a heating step at a first temperature for a first time period to induce material interactions at an accelerated rate, followed by cooling the sample to a second temperature and maintaining the second temperature for a time of sufficient duration such that relaxation occurs. Then the sample undergoes a heating process at a third temperature for a time sufficient to nucleate a predetermined number of voids, followed by heating the sample runner at a fourth temperature, less than than the third temperature, to propagate the voids such that a maximum void size is determined. Void distribution is preferably monitored by optical and scanning electron microscopy. By analyzing the void size distribution data for the isothermal void propagation annealing, a measure of the long term reliability is provided.

    摘要: The method of forming runners having superior stress migration characteristics is disclosed. A blanket layer of conductive material is deposited over a dielectric. A blanket layer is subjected to a blanket-etch back procedure, thereby reducing its thickness by approximately half. The remaining layer is then patterned to form runners. Resulting runners have a superior grain structure and greater resistance to electromigration and stress migration.
