摘要： Embodiments of the present invention relate to the analysis of the components of one or more gases, for example a gas mixture sampled from a semiconductor manufacturing process such as plasma etching or plasma enhanced chemical vapor deposition (PECVD). Particular embodiments provide sufficient power to a plasma of the sample, to dissociate a large number of the molecules and molecular fragments into individual atoms. With sufficient power (typically a power density of between 3-40 W/cm3) delivered into the plasma, most of the emission peaks result from emission of individual atoms, thereby creating spectra conducive to simplifying the identification of the chemical composition of the gases under investigation. Such accurate identification of components of the gas may allow for the precise determination of the stage of the process being performed, and in particular for detection of process endpoint.

摘要： Method and system for detecting endpoint for a plasma etch process are provided. In accordance with one embodiment, the method provides a semiconductor substrate having a film to be processed thereon. The film is processed in a plasma environment during a time period to provide for device structures. Information associated with the plasma process is collected. The information is characterized by a first signal intensity. Information on a change in the first signal intensity is extracted. The change in the first signal intensity has a second signal intensity. The change in signal intensity at the second signal intensity is associated to an endpoint of processing the film in the plasma environment. The second signal intensity may be about 0.25% and less of the first signal intensity.

摘要： Embodiments of the present invention employ measurement of argon as the means to detect the presence of an atmospheric leak in a processing chamber. Argon detected inside the process chamber is conclusive evidence of a leak. Furthermore, the amount of detected argon provides information on the rate of air entering through the leak. In one embodiment, leak detection takes place in the main plasma inside the processing chamber. In another embodiment, leak detection takes place in the self-contained plasma generated in a remote plasma sensor. Additional measurements can be performed, such as measuring the amount of oxygen, and/or the presence of moisture to help in detecting and quantifying outgassing from the processing chamber.

摘要： An embodiment of a method in accordance with the present invention to determine the flow rate of a second gas relative to a first gas, comprises, setting a flow of a first gas to a known level, taking a first measurement of the first gas with a measurement technique sensitive to a concentration of the first gas, and establishing a flow of a second gas mixed with the first gas. A second measurement of the first gas is taken with a measurement technique that is sensitive to the concentration of the first gas, and the flow of the second gas is determined by a calculation involving a difference between the first measurement and the second measurement. In alternative embodiments, the first measurement may be taken of a flow of two or more gases combined, with the second measurement taken with one of the gases removed from the mixture. Certain embodiments of methods of the present invention may be employed in sequence in order to determine flow rates of more than two gases.

摘要： The invention provides a method of processing a wafer using Ion Energy (IE)-related multilayer process sequences and Ion Energy Controlled Multi-Input/Multi-Output (IEC-MIMO) models and libraries that can include one or more measurement procedures, one or more IEC-etch sequences, and one or more Ion Energy Optimized (IEO) etch procedures. The IEC-MIMO process control uses dynamically interacting behavioral modeling between multiple layers and/or multiple IEC etch sequences. The multiple layers and/or the multiple IEC etch sequence can be associated with the creation of lines, trenches, vias, spacers, contacts, and gate structures that can be created using IEO etch procedures.
