摘要： A method of forming a silicon carbide layer for use in integrated circuit fabrication processes is provided. The silicon carbide layer is formed by reacting a gas mixture comprising a silicon source, a carbon source, and a dopant in the presence of an electric field. The as-deposited silicon carbide layer has a compressibility that varies as a function of the amount of dopant present in the gas mixture during later formation.

摘要： A stressed film is formed on a substrate. The substrate is placed in a process zone and a plasma is formed of a process gas provided in the process zone, the process gas having silicon-containing gas and nitrogen-containing gas. A diluent gas such as nitrogen can also be added. The as-deposited stressed material can be exposed to ultraviolet radiation or electron beams to increase the stress value of the deposited material. In addition or in the alternative, a nitrogen plasma treatment can be used to increase the stress value of the material during deposition. Pulsed plasma methods to deposit stressed materials are also described.
