Dry stripping of boron carbide hardmask
Embodiments of the disclosure generally relate to a method for dry stripping a boron carbide layer deposited on a semiconductor substrate. In one embodiment, the method includes loading the substrate with the boron carbide layer into a pressure vessel, exposing the substrate to a processing gas comprising an oxidizer at a pressure between about 500 Torr and 60 bar, heating the pressure vessel to a temperature greater than a condensation point of the processing gas and removing one or more products of a reaction between the processing gas and the boron carbide layer from the pressure vessel.

Carbon Gapfill Films
Methods are described for forming flowable carbon layers on a semiconductor substrate. A local excitation (such as a plasma in PECVD) may be applied as described herein to a carbon-containing precursor to form a flowable carbon film on a substrate. A remote excitation method has also been found to produce flowable carbon films by exciting a stable precursor to produce a radical precursor which is then combined with an unexcited carbon-containing precursor in the substrate processing region. An optional post deposition plasma exposure may also cure or solidify the flowable film after deposition. Methods for forming air gaps using the flowable films described herein are also described.
Methods to reduce material surface roughness
Exemplary deposition methods may include delivering a silicon-containing precursor and a boron-containing precursor to a processing region of a semiconductor processing chamber. The methods may include providing a hydrogen-containing precursor with the silicon-containing precursor and the boron-containing precursor. A flow rate ratio of the hydrogen-containing precursor to either of the silicon-containing precursor or the boron-containing precursor is greater than or about 1:1. The methods may include forming a plasma of all precursors within the processing region of a semiconductor processing chamber. The methods may include depositing a silicon-and-boron material on a substrate disposed within the processing region of the semiconductor processing chamber.
