    摘要: Copper precursors useful for depositing copper or copper-containing films on substrates, e.g., microelectronic device substrates or other surfaces. The precursors includes copper compounds of various classes, including copper borohydrides, copper compounds with cyclopentadienyl-type ligands, copper compounds with cyclopentadienyl-type and isocyanide ligands, and stabilized copper hydrides. The precursors can be utilized in solid or liquid forms that are volatilized to form precursor vapor for contacting with the substrate, to form deposited copper by techniques such as chemical vapor deposition (CVD), atomic layer deposition (ALD) or rapid vapor deposition (digital CVD).

    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.
