    摘要: Embodiments of methods for depositing silicon germanium (SiGe) layers on a substrate are disclosed herein. In some embodiments, the method may include depositing a first layer comprising silicon and germanium (e.g., a seed layer) atop the substrate using a first precursor comprising silicon and chlorine; and depositing a second layer comprising silicon and germanium (e.g., a bulk layer) atop the silicon germanium seed layer using a second precursor comprising silicon and hydrogen. In some embodiments, the first silicon precursor gas may comprise at least one of dichlorosilane (H2SiCl2), trichlorosilane (HSiCl3), or silicon tetrachloride (SiCl4). In some embodiments, the second silicon precursor gas may comprise at least one of silane (SiH4), or disilane (Si2H6).

    摘要: Methods and apparatus for processing a substrate are provided herein. In some embodiments, a method of processing a substrate may include providing a substrate having at least one of a defect or a contaminant disposed on or near a surface of the substrate; and selectively annealing a portion of the substrate with a laser beam in the presence of a process gas comprising hydrogen. The laser beam may be moved over the substrate or continuously, or in a stepwise fashion. The laser beam may be applied in a continuous wave or pulsed mode. The process gas may further comprise an inert gas, such as, at least one of helium, argon, or nitrogen. A layer of material may be subsequently deposited atop the annealed substrate.

    摘要: Embodiments of the invention generally provide a method for depositing a film containing silicon (Si) and nitrogen (N). In one embodiment, the method includes heating a substrate disposed in a processing chamber to a temperature less than about 650 degrees Celsius, flowing a nitrogen-containing gas into the processing chamber, flowing a silicon-containing gas into the processing chamber, and depositing a SiN-containing layer on a substrate. The silicon-containing gas is at least one of a gas identified as NR2—Si(R′2)—Si(R′2)—NR2 (amino(di)silanes), R3—Si—N═N═N (silyl azides), R′3—Si—NR—NR2 (silyl hydrazines) or 1,3,4,5,7,8-hexamethytetrasiliazane, wherein R and R′ comprise at least one functional group selected from the group of a halogen, an organic group having one or more double bonds, an organic group having one or more triple bonds, an aliphatic alkyl group, a cyclical alkyl group, an aromatic group, an organosilicon group, an alkyamino group, or a cyclic group containing N or Si.
