摘要： The present invention provides a method and system for providing contact management to participants engaged in a communication session. The invention permits chat session participants to a communication session to determine common contacts that exists between the chat session participants. Dependent on the accessibility of the particular chat session participants' contact list, other chat session participants to the communication session can view the information located in the contact list. Moreover, a particular chat session participant to the communication session can give either a particular chat session participant or all the chat session participants to the communication session permission to modify their contact list. Permission to access or modify contact lists for chat session participants can be defined prior to establishment of the communication session and/or changed during the communication session. Changes relating to whether a particular contact list is accessible and/or modifiable can be initiated by the chat session participant associated with the contact list. Additionally, such changes can be initiated by a request from a chat session participants to modify the contact records in a particular contact list. The invention can be applicable to systems which can include, but is not limited to, chat rooms, instant messaging, and call conferencing.

摘要： Embodiments of the invention provide methods for forming conductive materials within contact features on a substrate by depositing a seed layer within a feature and subsequently filling the feature with a copper-containing material during an electroless deposition process. In one example, a copper electroless deposition solution contains levelers to form convexed or concaved copper surfaces. In another example, a seed layer is selectively deposited on the bottom surface of the aperture while leaving the sidewalls substantially free of the seed material during a collimated PVD process. In another example, the seed layer is conformably deposited by a PVD process and subsequently, a portion of the seed layer and the underlayer are plasma etched to expose an underlying contact surface. In another example, a ruthenium seed layer is formed on an exposed contact surface by an ALD process utilizing the chemical precursor ruthenium tetroxide.

摘要： A method for the in situ cleaning of a semiconductor deposition chamber utilized for the deposition of a semiconductor material such as titanium or titanium nitride comprising, between wafers, introducing chlorine gas into the chamber at elevated temperature, purging the chamber with an inert gas and evacuating it before introduction of the next wafer. A two-stage between wafer cleaning process is carried out by introducing chlorine into the chamber at elevated temperature, thereafter initiating a plasma without removing the chlorine, purging the chamber with an inert gas and evacuating it before introduction of the next wafer. In a preferred embodiment, a thin protective film of titanium is deposited on the inner surfaces of the chamber prior to utilizing the chamber for the deposition of such material. The protective layer is replenished following each two-stage cleaning.

摘要： A semiconductor processing chamber is cleaned by introducing a cleaning gas into a processing chamber, striking a plasma in a remote plasma source that is in communication with the processing chamber, measuring the impedance of the plasma, vaporizing a ruthenium containing deposit on a surface of the processing chamber to form a ruthenium containing gas mixture, and flowing the gas mixture through an analyzer and into an exhaust collection assembly. The measurement of the impedance of the plasma in combination with the ruthenium concentration provides an accurate indication of chamber cleanliness.

摘要： A method of forming a titanium nitride (TiN) layer using a reaction between ammonia (NH3) and titanium tetrachloride (TiCl4). In one embodiment, an NH3:TiCl4 ratio of about 8.5 is used to deposit a TiN layer at a temperature of about 500° C. at a pressure of about 20 torr. In another embodiment, a composite TiN layer is formed by alternately depositing TiN layers of different thicknesses, using process conditions having different NH3:TiCl4 ratios. In one preferred embodiment, a TiN layer of less than about 20 Å is formed at an NH3:TiCl4 ratio of about 85, followed by a deposition of a thicker TiN layer at an NH3:TiCl4 ratio of about 8.5. By repeating the alternate film deposition using the two different process conditions, a composite TiN layer is formed. This composite TiN layer has an improved overall step coverage and reduced stress, compared to a standard TiN process, and is suitable for small geometry plug fill applications.

摘要： Embodiments of the invention provide an apparatus configured to form a material during an atomic layer deposition (ALD) process, such as a plasma-enhanced ALD (PE-ALD) process. In one embodiment, a process chamber is configured to expose a substrate to a sequence of gases and plasmas during a PE-ALD process.

摘要： Embodiments of the invention provide a method for depositing ruthenium materials on a substrate by various vapor deposition processes, such as atomic layer deposition (ALD) and plasma-enhanced ALD (PE-ALD). In one aspect, the process has little or no initiation delay and maintains a fast deposition rate while forming a ruthenium material. The ruthenium material may be deposited with good step coverage, strong adhesion, and contains a low carbon concentration for high electrical conductivity. The method for depositing the ruthenium material on a substrate generally includes sequentially exposing the substrate to a pyrrolyl ruthenium precursor and a reagent during the ALD process. The pyrrolyl ruthenium precursor contains ruthenium and at least one pyrrolyl ligand. In some examples, the reagent may contain a plasma of ammonia, nitrogen, or hydrogen during a PE-ALD process. In other examples, a reducing gas may be used during a thermal ALD process.
