    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.

    摘要: Methods and apparatus for selective one-step nitridation of semiconductor substrates is provided. Nitrogen is selectively incorporated in silicon regions of a semiconductor substrate having silicon regions and silicon oxide regions by use of a selective nitridation process. Nitrogen containing radicals may be directed toward the substrate by forming a nitrogen containing plasma and filtering or removing ions from the plasma, or a thermal nitridation process using selective precursors may be performed. A remote plasma generator may be coupled to a processing chamber, optionally including one or more ion filters, showerheads, and radical distributors, or an in situ plasma may be generated and one or more ion filters or shields disposed in the chamber between the plasma generation zone and the substrate support.

    摘要: An oxide and an oxynitride films and their methods of fabrication are described. The oxide or the oxynitride film is grown on a substrate that is placed in a deposition chamber. A silicon source gas (or a silicon source gas with a nitridation source gas) and an oxidation source gas are decomposed in the deposition chamber using a thermal energy source. A silicon oxide (or an oxynitride) film is formed above the substrate wherein total pressure for the deposition chamber is maintained in the range of 50 Torr to 350 Torr and wherein a flow ratio for the silicon source gas (or the silicon source gas with the nitridiation source gas) and the oxidation source gas is in the range of 1:50 to 1:10000 during a deposition process.
