摘要: Methods and apparatus for post treating an oxide layer on a semiconductor substrate are disclosed. In one or more embodiments, the oxide layer is formed by thermal oxidation or plasma oxidation and treated with a plasma comprising helium. The helium-containing plasma may also include hydrogen, neon, argon and combinations thereof. In one or more embodiments, a SiO2 oxide layer is formed on a silicon substrate and treated with a plasma to improve the interface between the silicon substrate and the SiO2 oxide layer.

摘要: Methods for processing substrates are provided herein. In some embodiments, a method for processing a substrate includes providing a substrate having an oxide layer disposed thereon, the oxide layer including one or more defects; and exposing the oxide layer to a plasma formed from a process gas comprising an oxygen-containing gas to repair the one or more defects. In some embodiments, the oxide layer may be formed on the substrate. In some embodiments, forming the oxide layer further comprises depositing the oxide layer atop the substrate. In some embodiments, forming the oxide layer further comprises thermally oxidizing the surface of the substrate to form the oxide layer. In some embodiments, a processing temperature is maintained at about 700 degrees Celsius or below during the thermal oxidation of the surface.
