Abstract: Embodiments of the present disclosure describe semiconductor devices with ruthenium phosphorus thin films and further describe the processes to deposit the thin films. The thin films may be deposited in a gate stack of a transistor device or in an interconnect structure. The processes to deposit the films may include chemical vapor deposition and may include ruthenium precursors. The precursors may contain phosphorus. A co-reactant may be used during deposition. A co-reactant may include a phosphorus based compound. A gate material may be deposited on the film in a gate stack. The ruthenium phosphorus film may be a metal diffusion barrier and an adhesion layer, and the film may be a work function metal for some embodiments. Other embodiments may be described and/or claimed.

Abstract: Organometallic precursors may be utilized to form titanium silicon nitride films that act as heaters for phase change memories. By using a combination of TDMAT and TrDMASi, for example in a metal organic chemical vapor deposition chamber, a relatively high percentage of silicon may be achieved in reasonable deposition times, in some embodiments. In one embodiment, two separate bubblers may be utilized to feed the two organometallic compounds in gaseous form to the deposition chamber so that the relative proportions of the precursors can be readily controlled.

Abstract: Noble metal may be used as a non-oxidizing diffusion barrier to prevent diffusion from copper lines. A diffusion barrier may be formed of a noble metal formed over an adhesion promoting layer or by a noble metal cap over an oxidizable diffusion barrier. The copper lines may also be covered with a noble metal.

Abstract: Methods and associated structures of forming a microelectronic device are described. Those methods may include introducing a first metal source, a second metal source and an oxygen source into a chamber and then forming a ternary oxide film comprising a first percentage of the first metal, a second percentage of the second metal, and a third percentage of oxygen.

Abstract: A deliberately engineered placement and size constraint (molecular weight distribution) of photoacid generators, solubility switches, photoimageable species, and quenchers forms individual pixels within a photoresist. Upon irradiation, a self-contained reaction occurs within each of the individual pixels that were irradiated to pattern the photoresist. These pixels may take on a variety of forms including a polymer chain, a bulky cluster, a micelle, or a micelle formed of several polymer chains. Furthermore, these pixels may be designed to self-assemble onto the substrate on which the photoresist is applied.

Abstract: A method for forming a nickel silicide layer on a MOS device with a low carbon content comprises providing a substrate within an ALD reactor and performing an ALD process cycle to form a nickel layer on the substrate, wherein the ALD process cycle comprises pulsing a nickel precursor into the reactor, purging the reactor after the nickel precursor, pulsing a mixture of hydrogen and silane into the reactor, and purging the reactor after the hydrogen and silane pulse. The ALD process cycle can be repeated until the nickel layer reaches a desired thickness. The silane used in the ALD process functions as a getterer for the advantageous carbon, resulting in a nickel layer that has a low carbon content. The nickel layer may then be annealed to form a nickel silicide layer with a low carbon content.
