    摘要: The present invention is directed to improving defect performance in semiconductor processing systems. In specific embodiments, an apparatus for processing semiconductor substrates comprises a chamber defining a processing region therein, and a substrate support disposed in the chamber to support a semiconductor substrate. At least one nozzle extends into the chamber to introduce a process gas into the chamber through a nozzle opening. The apparatus comprises at least one heat shield, each of which is disposed around at least a portion of one of the at least one nozzle. The heat shield has an extension which projects distally of the nozzle opening of the nozzle and which includes a heat shield opening for the process gas to flow therethrough from the nozzle opening. The heat shield decreases the temperature of nozzle in the processing chamber for introducing process gases therein to reduce particles.

    摘要: A method of depositing an insulating film over a substrate having a gap formed between two adjacent raised features. The method includes depositing one portion of the insulating film over the substrate and in the gap using a high density plasma process that has simultaneous deposition and sputtering components and depositing another portion of the insulating film over the substrate and in the gap using an atomic layer deposition process. In some embodiments the portion of the film deposited by an atomic layer deposition process is deposited over the portion of the film deposited using a high density plasma CVD technique. In other embodiments, the portion of the film deposited by a high density plasma CVD process is deposited over the portion of the film deposited using an atomic layer deposition process.

    摘要: A method of depositing a silica glass insulating film over a substrate. In one embodiment the method comprises exposing the substrate to a silicon-containing reactant introduced into a chamber in which the substrate is disposed such that one or more layers of the silicon-containing reactant are adsorbed onto the substrate; purging or evacuating the chamber of the silicon-containing reactant; converting the silicon-containing reactant into a silica glass insulating compound by exposing the substrate to oxygen radicals formed from a second reactant while biasing the substrate to promote a sputtering effect, wherein an average atomic mass of all atomic constituents in the second reactant is less than or equal to an average atomic mass of oxygen; and repeating the exposing, purging/evacuating and exposing sequence a plurality of times until a desired film thickness is reached.

    摘要: A method of filling a gap formed between adjacent raised surfaces on a substrate. In one embodiment the method comprises depositing a boron-doped silica glass (BSG) layer over the substrate to partially fill the gap using a thermal CVD process; exposing the BSG layer to a steam ambient at a temperature above the BSG layer's Eutectic temperature; removing an upper portion of the BSG layer by exposing the layer to a fluorine-containing etchant; and depositing an undoped silica glass (USG) layer over the BSG layer to fill the remainder of the gap.

The gas distribution plate includes a plurality of through-holes, which are typically crescent-shaped. Through-holes which have been formed in the solid yttrium oxide-comprising substrate by ultrasonic drilling perform particularly well. The solid yttrium oxide-comprising substrate typically comprises at least 99.9% yttrium oxide, and has a density of at least 4.92 g/cm3, a water absorbency of about 0.02% or less, and an average grain size within the range of about 10 μm to about 25 μm. Also disclosed herein are methods for fabricating and cleaning the yttrium oxide-comprising gas distribution plate.

    摘要: A process is provided for depositing an silicon oxide film on a substrate disposed in a process chamber. A process gas that includes a halogen source, a fluent gas, a silicon source, and an oxidizing gas reactant is flowed into the process chamber. A plasma having an ion density of at least 1011 ions/cm3 is formed from the process gas. The silicon oxide film is deposited over the substrate with a halogen concentration less than 1.0%. The silicon oxide film is deposited with the plasma using a process that has simultaneous deposition and sputtering components. The flow rate of the halogen source to the process chamber to the flow rate of the silicon source to the process chamber is substantially between 0.5 and 3.0.
