    摘要: Embodiments of the invention generally provide a method for depositing silicon-containing films. In one embodiment, a method for depositing silicon-containing material film on a substrate includes flowing a nitrogen and carbon containing chemical into a deposition chamber, flowing a silicon-containing source chemical having silicon-nitrogen bonds into the processing chamber, and heating the substrate disposed in the chamber to a temperature less than about 550 degrees Celsius. In another embodiment, the silicon containing chemical is trisilylamine and the nitrogen and carbon containing chemical is (CH3)3—N.

    摘要: Embodiments of methods for fabricating a silicon nitride stack on a semiconductor substrate are provided herein. In one embodiment, a method for fabricating a silicon nitride stack on a semiconductor substrate includes depositing a base layer comprising silicon nitride on the substrate using a first set of process conditions that selectively control the stress of the base layer; and depositing an upper layer comprising silicon nitride using a second set of process conditions that selectively control at least one of an oxidation resistance and a refractive index of the upper layer.
