  • Patent number: 11232947
    Abstract: An ammonium fluoride gas may be used to form a protection layer for one or more interlayer dielectric layers, one or more insulating caps, and/or one or more source/drain regions of a semiconductor device during a pre-clean etch process. The protection layer can be formed through an oversupply of nitrogen trifluoride during the pre-clean etch process. The oversupply of nitrogen trifluoride causes an increased formation of ammonium fluoride, which coats the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) with a thick protection layer. The protection layer protects the interlayer dielectric layer(s), the insulating cap(s), and/or the source/drain region(s) during the pre-clean process from being etched by fluorine ions formed during the pre-clean process.

  • Publication number: 20210296168
    Abstract: Generally, examples are provided relating to conductive features that include a barrier layer, and to methods thereof. In an embodiment, a metal layer is deposited in an opening through a dielectric layer(s) to a source/drain region. The metal layer is along the source/drain region and along a sidewall of the dielectric layer(s) that at least partially defines the opening. The metal layer is nitrided, which includes performing a multiple plasma process that includes at least one directional-dependent plasma process. A portion of the metal layer remains un-nitrided by the multiple plasma process. A silicide region is formed, which includes reacting the un-nitrided portion of the metal layer with a portion of the source/drain region. A conductive material is disposed in the opening on the nitrided portions of the metal layer.
