Abstract: Chromium containing precursors and methods of forming chromium-containing thin films are described. The chromium precursor has a chromium-diazadiene bond or cyclopentadienyl ligand and is homoleptic or heteroleptic. A suitable reactant is used to provide one of a metallic chromium film or a film comprising one or more of an oxide, nitride, carbide, boride and/or silicide. Methods of forming ternary materials comprising chromium with two or more of oxygen, nitrogen, carbon, boron, silicon, titanium, ruthenium and/or tungsten are also described. Methods of filling gaps in a substrate with a chromium-containing film are also described.

Abstract: Embodiments include a method of processing a hardmask that includes forming an alloyed carbon hardmask over an underlying layer. In an embodiment, the alloyed carbon hardmask is alloyed with metallic-carbon fillers. The embodiment further includes patterning the alloyed carbon hardmask and transferring the pattern of the alloyed carbon hardmask into the underlying layer. According to an embodiment, the method may further include removing the metallic component of the metallic-carbon fillers from the alloyed carbon hardmask to form a porous carbon hardmask. Thereafter, the porous hardmask may be removed. In an embodiment, the metallic component of the metallic-carbon fillers may include flowing a processing gas into a chamber that volatizes the metallic component of the metallic-carbon fillers.
