摘要： Exemplary deposition methods may include delivering a boron-containing precursor and a nitrogen-containing precursor to a processing region of a semiconductor processing chamber. The methods may include providing a hydrogen-containing precursor with the boron-containing precursor and the nitrogen-containing precursor. A flow rate ratio of the hydrogen-containing precursor to either of the boron-containing precursor or the nitrogen-containing precursor may be greater than or about 2:1. The methods may include forming a plasma of all precursors within the processing region of the semiconductor processing chamber. The methods may include depositing a boron-and-nitrogen material on a substrate disposed within the processing region of the semiconductor processing chamber.

摘要： Exemplary methods of semiconductor processing may include forming a layer of silicon nitride on a semiconductor substrate. The layer of silicon nitride may be characterized by a first roughness. The methods may include performing a post-deposition treatment on the layer of silicon nitride. The methods may include reducing a roughness of the layer of silicon nitride such that the layer of silicon nitride may be characterized by a second roughness less than the first roughness.

摘要： Methods for forming a SiBN film comprising depositing a film on a feature on a substrate. The method comprises in a first cycle, depositing a SiB layer on a substrate in a chamber using a chemical vapor deposition process, the substrate having at least one feature thereon, the at least one feature comprising an upper surface, a bottom surface and sidewalls, the SiB layer formed on the upper surface, the bottom surface and the sidewalls. In a second cycle, the SiB layer is treated with a plasma comprising a nitrogen-containing gas to form a conformal SiBN film.

摘要： Memory devices and methods of forming memory devices are described. The memory devices comprise a silicon nitride hard mask layer on a ruthenium layer. Forming the silicon nitride hard mask layer on the ruthenium comprises pre-treating the ruthenium layer with a plasma to form an interface layer on the ruthenium layer; and forming a silicon nitride layer on the interface layer by plasma-enhanced chemical vapor deposition (PECVD). Pre-treating the ruthenium layer, in some embodiments, results in the interface layer having a reduced roughness and the memory device having a reduced resistivity compared to a memory device that does not include the interface layer.
