    摘要: A method for forming sidewall spacers on a gate stack by depositing one or more layers of silicon containing materials using PECVD process(es) on a gate structure to produce a spacer having an overall k value of about 3.0 to about 5.0. The silicon containing materials may be silicon carbide, oxygen doped silicon carbide, nitrogen doped silicon carbide, carbon doped silicon nitride, nitrogen doped silicon oxycarbide, or combinations thereof. The deposition is performed in a plasma enhanced chemical vapor deposition chamber and the deposition temperature is less than 450° C. The sidewall spacers so produced provide good capacity resistance, as well as excellent structural stability and hermeticity.

    摘要: A dual channel gas distributor can simultaneously distribute plasma species of an first process gas and a non-plasma second process gas into a process zone of a substrate processing chamber. The gas distributor has a localized plasma box with a first inlet to receive a first process gas, and opposing top and bottom plates that are capable of being electrically biased relative to one another to define a localized plasma zone in which a plasma of the first process gas can be formed. The top plate has a plurality of spaced apart gas spreading holes to spread the first process gas across the localized plasma zone, and the bottom plate has a plurality of first outlets to distribute plasma species of the plasma of the first process gas into the process zone. A plasma isolated gas feed has a second inlet to receive the second process gas and a plurality of second outlets to pass the second process gas into the process zone. A plasma isolator is between the second inlet and second outlets to prevent formation of a plasma of the second process gas in the plasma isolated gas feed.

    摘要: Methods are provided for depositing amorphous carbon materials. In one aspect, the invention provides a method for processing a substrate including forming a dielectric material layer on a surface of the substrate, depositing an amorphous carbon layer on the dielectric material layer by introducing a processing gas comprises one or more hydrocarbon compounds and an argon carrier gas, and generating a plasma of the processing gas by applying power from a dual-frequency RF source, etching the amorphous carbon layer to form a patterned amorphous carbon layer, and etching feature definitions in the dielectric material layer corresponding to the patterned amorphous carbon layer. The amorphous carbon layer may act as an etch stop, an anti-reflective coating, or both.
