    摘要: Methods of making a silicon oxide layer on a substrate are described. The methods may include forming the silicon oxide layer on the substrate in a reaction chamber by reacting an atomic oxygen precursor and a silicon precursor and depositing reaction products on the substrate. The atomic oxygen precursor is generated outside the reaction chamber. The methods also include heating the silicon oxide layer at a temperature of about 600° C. or less, and exposing the silicon oxide layer to an induced coupled plasma. Additional methods are described where the deposited silicon oxide layer is cured by exposing the layer to ultra-violet light, and also exposing the layer to an induced coupled plasma.

    摘要: Methods of forming a dielectric layer where the tensile stress of the layer is increased by a plasma treatment at an elevated position are described. In one embodiment, oxide and nitride layers are deposited on a substrate and patterned to form an opening. A trench is etched into the substrate. The substrate is transferred into a chamber suitable for dielectric deposition. A dielectric layer is deposited over the substrate, filling the trench and covering mesa regions adjacent to the trench. The substrate is raised to an elevated position above the substrate support and exposed to a plasma which increases the tensile stress of the substrate. The substrate is removed from the dielectric deposition chamber, and portions of the dielectric layer are removed so that the dielectric layer is even with the topmost portion of the nitride layer. The nitride and pad oxide layers are removed to form the STI structure.

    摘要: Methods are disclosed for activating dopants in a doped semiconductor substrate. A carbon precursor is flowed into a substrate processing chamber within which the doped semiconductor substrate is disposed. A plasma is formed from the carbon precursor in the substrate processing chamber. A carbon film is deposited over the substrate with the plasma. A temperature of the substrate is maintained while depositing the carbon film less than 500° C. The deposited carbon film is exposed to electromagnetic radiation for a period less than 10 ms, and has an extinction coefficient greater than 0.3 at a wavelength comprised by the electromagnetic radiation.

    摘要: A plasma treatment process for increasing the tensile stress of a silicon wafer is described. Following deposition of a dielectric layer on a substrate, the substrate is lifted to an elevated position above the substrate receiving surface and exposed to a plasma treatment process which treats both the top and bottom surface of the wafer and increases the tensile stress of the deposited layer. Another embodiment of the invention involves biasing of the substrate prior to plasma treatment to bombard the wafer with plasma ions and raise the temperature of the substrate. In another embodiment of the invention, a two-step plasma treatment process can be used where the substrate is first exposed to a plasma at a processing position directly after deposition, and then raised to an elevated position where both the top and bottom of the wafer are exposed to the plasma.
