摘要： Method and apparatus for abating F2 from by-products generated during cleaning of a processing chamber. F2 abatement is efficiently performed by directly injecting H2 in line with a foreline exiting the processing chamber. A tube which is highly resistant to oxidation and corrosive gases, even at high temperature, is connected in line with the foreline as part of the exhaust line of the processing chamber. A cooling jacket may be provided for cooling the tube, since the reaction between F2 and H2 is exothermic. A pressure monitoring arrangement may also be employed to insure that pressure within a hydrogen line, that feeds the injection of H2 into the tube, does not exceed a predetermined pressure value.

摘要： Methods of removing metal hardmasks in the presence of ultra low-k dielectric films are described. In an example, a method of patterning a low-k dielectric film includes forming a pattern in a metal nitride hardmask layer formed above a low-k dielectric film formed above a substrate. The method also includes etching, using the metal nitride hardmask layer as a mask, the pattern at least partially into the low-k dielectric film, the etching involving using a plasma etch based on SiFx. The etching also involves forming an SiOx passivation layer at least on sidewalls of the low-k dielectric film formed during the etching. The method also includes removing the metal nitride hardmask layer by a dry etch process, where the SiOx passivation layer protects the low-k dielectric film during the removing.

摘要： Methods of multiple patterning of low-k dielectric films are described. For example, a method includes forming and patterning a first mask layer above a low-k dielectric layer, the low-k dielectric layer disposed above a substrate. A second mask layer is formed and patterned above the first mask layer. A pattern of the second mask layer is transferred at least partially into the low-k dielectric layer by modifying first exposed portions of the low-k dielectric layer with a first plasma process and removing the modified portions of the low-k dielectric layer. Subsequently, a pattern of the first mask layer is transferred at least partially into the low-k dielectric layer by modifying second exposed portions of the low-k dielectric layer with a second plasma process and removing the modified portions of the low-k dielectric layer.
