摘要:
Apparatus and methods for distributing gas in a semiconductor process chamber are provided. In an embodiment, a gas distributor for use in a gas processing chamber comprises a body. The body includes a baffle with a gas deflection surface to divert the flow of a gas from a first direction to a second direction. The gas deflection surface comprises a concave surface. The concave surface comprises at least about 75% of the surface area of the gas deflection surface. The concave surface substantially deflects the gas toward a chamber wall and provides decreased metal atom contamination from the baffle so that season times can be reduced.

A processing chamber is seasoned by providing a flow of season precursors to the processing chamber. A high-density plasma is formed from the season precursors by applying at least 7500 W of source power distributed with greater than 70% of the source power at a top of the processing chamber. A season layer having a thickness of at least 5000 Å is deposited at one point using the high-density plasma. Each of multiple substrates is transferred sequentially into the processing chamber to perform a process that includes etching. The processing chamber is cleaned between sequential transfers of the substrates.

Methods are disclosed for depositing a silicon oxide film on a substrate disposed in a substrate processing chamber. The substrate has a gap formed between adjacent raised surfaces. A silicon-containing gas, an oxygen-containing gas, and a fluent gas are flowed into the substrate processing chamber. A high-density plasma is formed from the silicon-containing gas, the oxygen-containing gas, and the fluent gas. A first portion of the silicon oxide film is deposited using the high-density plasma at a deposition rate between 900 and 6000 Å/min and with a deposition/sputter ratio greater than 30. The deposition/sputter ratio is defined as a ratio of a net deposition rate and a blanket sputtering rate to the blanket sputtering rate. Thereafter, a portion of the deposited first portion of the silicon oxide film is etched. A second portion of the silicon oxide film is deposited over the etched portion of the silicon oxide film.

A method of forming a dielectric material in a substrate gap using a high-density plasma is described. The method may include depositing a first portion of the dielectric material into the gap with the high-density plasma. The deposition may form a protruding structure that at least partially blocks the deposition of the dielectric material into the gap. The first portion of dielectric material is exposed to an etchant that includes reactive species from a mixture that includes NH3 and NF3. The etchant forms a solid reaction product with the protruding structure, and the solid reaction product may be removed from the substrate. A final portion of the dielectric material may be deposited in the gap with the high-density plasma.

摘要:
A video bit rate control method. SUBGOPs are defined as sets of two to four frames in a GOP. For example, if the GOP comprises IBBPBBPBBPBB frames, each of the SUBGOPs is defined as a set of the IBBP or BBP frames. Before bit assignment is performed with respect to frames to be coded, it is checked whether a scene change is present with respect to frames in successive ones of the SUBGOPs. If it is checked that the scene change is not present, a bit rate is controlled in a conventional manner. In the case where the scene change is present, a smaller bits than that in the conventional manner is assigned to frames with no scene change and a relatively large bit amount is assigned to a frame with the scene change. Therefore, according to the present invention, the video bit rate control method has the effect of preventing a degradation in a picture quality due to the scene change.

Disclosed are methods and apparatus for displaying information relating to a portion of a multimedia presentation. A progress bar is provided and displayed. A length of the progress bar is representative of a duration of the multimedia presentation. A user selects a first and a second point in the multimedia presentation, thereby defining a portion of the presentation. Depending on the selection, one or more communications (e.g., comments, online postings, etc.) may be identified. Each of these communications may have been composed in relation to at least a point of the multimedia presentation that is within the defined portion. Information depending on those identified communications may then be displayed to the user.
摘要:
Incoming audio from mobile devices can be centrally processed, where a server can filter background noise in real time, such as by using an XOR function. Instead of discarding the filtered noise, however, it can be processed in parallel to dynamically construct an acoustic map of the environment. The acoustic map can be generated from an aggregation of sound data from multiple devices positioned in a geographic environment. The acoustic map can be linked to a configurable set of rules, conditions, and events, which can cause dynamic adjustments to be made to a workforce task management system. For example, employee availability can be assessed using the acoustic map and workforce tasks can be assigned based in part upon this availability.
摘要:
A method of suppressing the etch rate for exposed silicon-and-nitrogen-containing material on patterned heterogeneous structures is described and includes a two stage remote plasma etch. The etch selectivity of silicon relative to silicon nitride and other silicon-and-nitrogen-containing material is increased using the method. The first stage of the remote plasma etch reacts plasma effluents with the patterned heterogeneous structures to form protective solid by-product on the silicon-and-nitrogen-containing material. The plasma effluents of the first stage are formed from a remote plasma of a combination of precursors, including nitrogen trifluoride and hydrogen (H2). The second stage of the remote plasma etch also reacts plasma effluents with the patterned heterogeneous structures to selectively remove material which lacks the protective solid by-product. The plasma effluents of the second stage are formed from a remote plasma of a fluorine-containing precursor.

A method of depositing a phosphosilicate glass (PSG) film on a substrate disposed in a substrate processing chamber includes depositing a first portion of the PSG film over the substrate using a high-density plasma process. Thereafter, a portion of the first portion of the PSG film may be etched back. The etch back process may include flowing a halogen precursor to the substrate processing chamber, forming a high-density plasma from the halogen precursor, and terminating flowing the halogen precursor after the etch back. The method also includes flowing a halogen scavenger to the substrate processing chamber to react with residual halogen in the substrate processing chamber, and exposing the first portion of the PSG film to a phosphorus-containing gas to provide a substantially uniform phosphorus concentration throughout the first portion of the PSG film.
