摘要： A replaceable gas nozzle is insertable in a gas distributor ring of a substrate processing chamber and that can be shielded within the chamber. The replaceable gas nozzle has a longitudinal ceramic body having a channel to direct the flow of the gas into the chamber. The ceramic body includes a first external thread to mate with the gas distributor ring, and a second external thread to receive a heat shield. The channel has an inlet to receive the gas from the gas distributor ring and a pinhole outlet to release the gas into the chamber. A heat shield can be used to shield the nozzle extending into the chamber. The heat shield has a hollow member configured to be coupled with the nozzle that has an internal dimension sufficiently large to be disposed around at least a portion of the nozzle. The hollow member also has an extension which projects distally of the outlet of the nozzle and a heat shield opening for the process gas to flow therethrough from the nozzle outlet.

摘要： Abstract of the Disclosure A deposition / etching /deposition process is provided for filling a gap in a surface of a substrate. A liner is formed over the substrate so that distinctive reaction products are formed when it is exposed to a chemical etchant. The detection of such reaction products thus indicates that the portion of the film deposited during the first etching has been removed to an extent that further exposure to the etchant may remove the liner and expose underlying structures. Accordingly, the etching is stopped upon detection of distinctive reaction products and the next deposition in the deposition /etching /deposition process is begun.

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： 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.
