Abstract: Methods of filling a gap on a substrate with silicon oxide are described. The methods may include the steps of introducing an organo-silicon precursor and an oxygen precursor to a deposition chamber, reacting the precursors to form a first silicon oxide layer in the gap on the substrate, and etching the first silicon oxide layer to reduce the carbon content in the layer. The methods may also include forming a second silicon oxide layer on the first layer, and etching the second layer to reduce the carbon content in the second layer. The silicon oxide layers are annealed after the gap is filled.

Abstract: 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.

Abstract: 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.

Abstract: A variety of techniques may be employed, separately or in combination, to improve the gap-filling performance of a dielectric material formed by chemical vapor deposition (CVD). In one approach, a first dielectric layer is deposited using sub-atmospheric chemical vapor deposition (SACVD), followed by a second dielectric layer deposited by high density plasma chemical vapor deposition (HDP-CVD) or plasma-enhanced chemical vapor deposition (PECVD). In another approach, a SACVD dielectric layer is deposited in the presence of reactive ionic species flowed from a remote plasma chamber into the processing chamber, which performs etching during the deposition process. In still another approach, high aspect trenches may be filled utilizing SACVD in combination with oxide layers deposited at high temperatures.

Abstract: 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.

Abstract: A method of depositing a film on a substrate disposed in a substrate processing chamber. The method includes depositing a first portion of the film by forming a high density plasma from a first gaseous mixture flown into the process chamber. The deposition processes is then stopped and part of the deposited first portion of the film is etched by flowing a halogen etchant into the processing chamber. Next, the surface of the etched film is passivated by flowing a passivation gas into the processing chamber, and then a second portion of the film is deposited over the first portion by forming a high density plasma from a second gaseous mixture flown into the process chamber. In one embodiment the passivation gas consists of an oxygen source with our without an inert gas.

Abstract: In a method for identifying an unknown product a library of absorbance spectra of known products is measured and stored in a library. A quick search using clustering techniques is conducted to narrow the search to a few products, followed by an exhaustive search of the spectra of the few products. More specifically, principal component analysis is applied to the absorbance spectra to generate product score vectors extending into principal component inside model space which are divided into clusters and subclusters in accordance with their relative proximity. Hyperspheres are constructed around each vector and an envelope is constructed to enclose each cluster surrounding the hyperspheres within the cluster. The absorbance spectrum of the unknown product to be identified is measured and an unknown product score vector is determined from the unknown product spectrum projecting in principal component inside model space of the clusters.
