摘要: The present disclosure provides a method of semiconductor fabrication including forming an inter-layer dielectric (ILD) layer on a semiconductor substrate. The ILD layer has an opening defined by sidewalls of the ILD layer. A spacer element is formed on the sidewalls of the ILD layer. A gate structure is formed in the opening adjacent the spacer element. In an embodiment, the sidewall spacer also for a decrease in the dimensions (e.g., length) of the gate structure formed in the opening.

摘要: An oxygen-free hydrogen plasma ashing process particularly useful for low-k dielectric materials based on hydrogenated silicon oxycarbide materials. The main ashing step includes exposing a previously etched dielectric layer to a plasma of hydrogen and optional nitrogen, a larger amount of water vapor, and a yet larger amount of argon or helium. Especially for porous low-k dielectrics, the main ashing plasma additionally contains a hydrocarbon gas such as methane. The main ashing may be preceded by a short surface treatment by a plasma of a hydrogen-containing reducing gas such as hydrogen and optional nitrogen.
