LOW-K ALD GAP-FILL METHODS AND MATERIAL

Various embodiments include methods to produce low dielectric-constant (low-k) films. In one embodiment, alternating ALD cycles and dopant materials are used to generate a new family of silicon low-k materials. Specifically, these materials were developed to fill high-aspect-ratio structures with re-entrant features. However, such films are also useful in blanket applications where conformal nanolaminates are applicable. Various embodiments also disclose SiOF as well as SiOCF, SiONF, GeOCF, and GeOF. Analogous films may include halide derivatives with iodine and bromine (e.g., replace “F” with “I” or “Br”). Other methods, chemistries, and techniques are disclosed.
