摘要： Incompatible materials, such as copper and nitrided barrier layers, may be adhered more effectively to one another. In one embodiment, a precursor of copper is deposited on the nitrided barrier. The precursor is then converted, through the application of energy, to copper which could not have been as effectively adhered to the barrier in the first place.

摘要： Described herein are metal gate electrode stacks including a low resistance metal cap in contact with a metal carbonitride diffusion barrier layer, wherein the metal carbonitride diffusion barrier layer is tuned to a particular work function to also serve as a work function metal for a pMOS transistor. In an embodiment, the work function-tuned metal carbonitride diffusion barrier prohibits a low resistance metal cap layer of the gate electrode stack from migrating into the MOS junction. In a further embodiment of the present invention, the work function of the metal carbonitride barrier film is modulated to be p-type with a pre-selected work function by altering a nitrogen concentration in the film.

摘要： An iodine-doped ruthenium barrier layer for use with copper interconnects within integrated circuits is formed using novel, iodine-containing ruthenium precursors in an ALD or CVD process. Ruthenium precursors that may be used include ruthenium containing carbonyls, arenes, cyclopentadienyls, and certain other ruthenium containing compounds. The ruthenium precursors include iodine to catalyze a subsequent copper metal deposition and to smooth the surface of the ruthenium layer. The iodine concentration across the thickness of the ruthenium barrier layer may be constant or may be graded.
