    摘要: Embodiments of the present invention provide methods, apparatuses, and devices related to chemical vapor deposition of silicon oxide. In one embodiment, a single-step deposition process is used to efficiently form a silicon oxide layer exhibiting high conformality and favorable gap-filling properties. During a pre-deposition gas flow stabilization phase and an initial deposition stage, a relatively low ratio of silicon-containing gas:oxidant deposition gas is flowed, resulting in formation of highly conformal silicon oxide at relatively slow rates. Over the course of the deposition process step, the ratio of silicon-containing gas:oxidant gas is increased, resulting in formation of less-conformal oxide material at relatively rapid rates during later stages of the deposition process step.

    摘要: A method of improving pattern loading in a deposition of a silicon oxide film is described. The method may include providing a deposition substrate to a deposition chamber, and adjusting a temperature of the deposition substrate to about 250° C. to about 325° C. An ozone containing gas may be introduced to the deposition chamber at a first flow rate of about 1.5 slm to about 3 slm, where the ozone concentration in the gas is about 6% to about 12%, by wt. TEOS may also be introduced to the deposition chamber at a second flow rate of about 2500 mgm to about 4500 mgm. The deposition rate of the silicon oxide film is controlled by a reaction rate of a reaction of the ozone and TEOS at a deposition surface of the substrate.

    摘要: A method of forming and removing a sacrificial oxide layer is described. The method includes forming a step on a substrate, where the step has a top and sidewalls. The method may also include forming the sacrificial oxide layer around the step by chemical vapor deposition of molecular oxygen and TEOS, where the oxide layer is formed on the top and sidewalls of the step. The method may also include removing a top portion of the oxide layer and the step; removing a portion of the substrate exposed by the removal of the step to form a etched substrate; and removing the entire sacrificial oxide layer from the etched substrate.
