    摘要: Methods and apparatus for protecting the dielectric layer sidewalls of openings, such as vias and trenches, in semiconductor substrates are provided. A pre-liner and a liner are deposited over the sidewalls of the openings as part of integrated processing sequences that either do not remove the photoresist until subsequent processing or remove the photoresist with a plasma etch that does not contaminate the sidewalls of the openings.

    摘要: Crystal lattice dislocations in material surrounding trench capacitors and other trench structures are avoided by alteration of stresses such as decreasing compressive stresses and/or development of persistent tensile forces within material deposited in the trench and thus at the material interface formed by the trench. Such alteration of stresses is achieved by volume reduction of a film deposited in the trench. The material is preferably a hydrogenated nitride of silicon, boron or silicon-carbon alloy which may be reduced in volume by partial or substantially complete dehydrogenation during subsequent heat treatment at temperatures where the film will exhibit substantial creep resistance. The amount of volume reduction can be closely controlled by control of concentration of hydrogen or other gas or volatile material in the film. Further fine adjustment of stresses can be achieved in combination with this mechanism by volume reduction of other materials which may be used, in part, to confine the film through other mechanisms such as annealing.

    摘要: An interconnect structure is provided that has improved electromigration resistance as well as methods of forming such an interconnect structure. The interconnect structure includes a composite M-MOx cap located at least on the upper surface of the Cu-containing material within the at least one opening. The composite M-MOx cap includes an upper region that is composed of the metal having a higher affinity for oxygen than copper and copper oxide and a lower region that is composed of a non-stoichiometric oxide of said metal.
