  • Publication number: 20160118340
    Abstract: Devices and methods for providing low-resistance interconnects in a semiconductor device are provided. Specifically, one or more embodiments of the present invention relate to disposing a conductive material in a trench without disposing a resistive barrier material between the conductive material and the sidewalls of the trench so that the conductive material takes up the full width of the trench. For example, the trench may be disposed over one or more contacts made of a barrier material such as titanium nitride that also acts as a seed, and the conductive material may be grown on top of the titanium nitride to fill the trench.

  • Patent number: 9306159
    Abstract: Memory devices and methods for fabricating memory devices have been disclosed. One such method includes forming the memory stack out of a plurality of elements. An adhesion species is formed on at least one sidewall of the memory stack wherein the adhesion species has a gradient structure that results in the adhesion species intermixing with an element of the memory stack to terminate unsatisfied atomic bonds of the element. The gradient structure further comprises a film of the adhesion species on an outer surface of the at least one sidewall. A dielectric material is implanted into the film of the adhesion species to form a sidewall liner.

  • Publication number: 20160093688
    Abstract: A multilayer source provides charge carriers to a multitier channel connector. The source includes a metal silicide layer on a substrate and a metal nitride layer between the metal silicide layer and the channel. The metal silicide and the metal nitride are processed without an intervening oxide layer between them. In one embodiment, the source further includes a silicon layer between the metal nitride layer and the channel. The silicon layer can also be processed without an intervening oxide layer. Thus, the source does not have an intervening oxide layer from the substrate to the channel.

  • Patent number: 9093367
    Abstract: Some embodiments include methods of forming one or more doped regions in a semiconductor substrate. Plasma doping may be used to form a first dopant to a first depth within the substrate. The first dopant may then be impacted with a second dopant to knock the first dopant to a second depth within the substrate. In some embodiments the first dopant is p-type (such as boron) and the second dopant is neutral type (such as germanium). In some embodiments the second dopant is heavier than the first dopant.
