    摘要: Embodiments of the invention generally relate to methods of dry stripping boron-carbon films. In one embodiment, alternating plasmas of hydrogen and oxygen are used to remove a boron-carbon film. In another embodiment, co-flowed oxygen and hydrogen plasma is used to remove a boron-carbon containing film. A nitrous oxide plasma may be used in addition to or as an alternative to either of the above oxygen plasmas. In another embodiment, a plasma generated from water vapor is used to remove a boron-carbon film. The boron-carbon removal processes may also include an optional polymer removal process prior to removal of the boron-carbon films. The polymer removal process includes exposing the boron-carbon film to NF3 to remove from the surface of the boron-carbon film any carbon-based polymers generated during a substrate etching process.

    摘要: Methods of depositing amorphous carbon films on substrates are provided herein. The methods reduce or prevent plasma-induced charge damage to the substrates from the deposition of the amorphous carbon films. In one aspect, an initiation layer of amorphous carbon is deposited at a low RF power level and/or at a low hydrocarbon compound/inert gas flow rate ratio before a bulk layer of amorphous carbon is deposited. After the deposition of the initiation layer, the RF power, hydrocarbon flow rate, and inert gas flow rate may be ramped to final values for the deposition of the bulk layer, wherein the RF power ramp rate is typically greater than the ramp rates of the hydrocarbon compound and of the inert gas. In another aspect, a method of minimizing plasma-induced charge damage includes depositing a seasoning layer on one or more interior surfaces of a chamber before the deposition of the amorphous carbon film on a substrate therein or coating the interior surfaces with an oxide or dielectric layer during manufacturing.

    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.
