摘要: Methods for formation of epitaxial layers containing silicon are disclosed. Specific embodiments pertain to the formation and treatment of epitaxial layers in semiconductor devices, for example, Metal Oxide Semiconductor Field Effect Transistor (MOSFET) devices. In specific embodiments, the formation of the epitaxial layer involves exposing a substrate in a process chamber to deposition gases including two or more silicon source such as silane and a higher order silane. Embodiments include flowing dopant source such as a phosphorus dopant, during formation of the epitaxial layer, and continuing the deposition with the silicon source gas without the phosphorus dopant.

摘要: An assembly comprises a multilayer nitride stack having nitride etch stop layers formed on top of one another, each of the nitride etch stop layers is formed using a film forming process. A method of making the multilayer nitride stack includes placing a substrate in a single wafer deposition chamber and thermally shocking the substrate momentarily prior to deposition. A first nitride etch stop layer is deposited over the substrate. A second nitride etch stop layer is deposited over the first nitride etch stop layer.
