  • Publication number: 20050235916
    Abstract: A substrate processing system is provided with a processing chamber, an alternating voltage supply, and an impedance matching network. The processing chamber holds a substrate during processing and the alternating voltage supply is connected with the processing chamber to capacitively couple energy to a plasma formed within the processing chamber. The impedance matching network is coupled with the alternating voltage supply and has a variable resistive element and a variable reactive element, whose states respectively define distinct real and imaginary parts of an impedance.

  • Publication number: 20050170104
    Abstract: We have discovered that is possible to tune the stress of a single-layer silicon nitride film by manipulating certain film deposition parameters. These parameters include: use of multiple (typically dual) power input sources operating within different frequency ranges; the deposition temperature; the process chamber pressure; and the composition of the deposition source gas. In particular, we have found that it is possible to produce a single-layer, thin (300 ? to 1000 ? thickness) silicon nitride film having a stress tuned to be within the range of about ?1.4 GPa (compressive) to about +1.5 GPa (tensile) by depositing the film by PECVD, in a single deposition step, at a substrate temperature within the range of about 375° C. to about 525 ° C., and over a process chamber pressure ranging from about 2 Torr to about 15 Torr.

  • Patent number: 5994678
    Abstract: The present invention provides systems, methods and apparatus for depositing titanium films at rates up to 200 .ANG./minute on semiconductor substrates from a titanium tetrachloride source. In accordance with an embodiment of the invention, a ceramic heater assembly with an integrated RF plane for bottom powered RF capability allows PECVD deposition at a temperature of at least 400.degree. C. for more efficient plasma treatment. A thermal choke isolates the heater from its support shaft, reducing the thermal gradient across the heater to reduce the risk of breakage and improving temperature uniformity of the heater. A deposition system incorporates a flow restrictor ring and other features that allow a 15 liters/minute flow rate through the chamber with minimal backside deposition and minimized deposition on the bottom of the chamber, thereby reducing the frequency of chamber cleanings, and reducing clean time and seasoning. Deposition and clean processes are also further embodiments of the present invention.
