Film deposition using tantalum precursors
Provided are methods of depositing tantalum-containing films via atomic layer deposition and/or chemical vapor deposition. The method comprises exposing a substrate surface to flows of a first precursor comprising TaCl.sub.xR.sub.5-x, TaBr.sub.xR.sub.5-x or TaI.sub.xR.sub.5-x, wherein R is a non-halide ligand, and a second precursor comprising an aluminum-containing compound, wherein x has a value in the range of 1 to 4. The R group may be C1-C5 alkyl, and specifically methyl. The resulting films comprise tantalum, aluminum and/or carbon. Certain other methods relate to reacting Ta.sub.2Cl.sub.10 with a coordinating ligand to provide TaCl.sub.5 coordinated to the ligand. A substrate surface may be exposed to flows of a first precursor and second precursor, the first precursor comprising the TaCl.sub.5 coordinated to a ligand, the second precursor comprising an aluminum-containing compound.

CARBON BASED DEPOSITIONS USED FOR CRITICAL DIMENSION CONTROL DURING HIGH ASPECT RATIO FEATURE ETCHES AND FOR FORMING PROTECTIVE LAYERS
Fabricating a semiconductor substrate by (a) vertical etching a feature having sidewalls and a depth into one or more layers formed on the semiconductor substrate and (b) depositing an amorphous carbon liner onto the sidewalls of the feature. Steps (a) and optionally (b) are iterated until the vertical etch feature has reached a desired depth. With each iteration of (a), the feature is vertical etched deeper into the one or more layers, while the amorphous carbon liner resists lateral etching of the sidewalls of the feature. With each optional iteration of (b), the deposited amorphous carbon liner on the sidewalls of the feature is replenished.
