Abstract: Embodiments of the present technology may include a method of etching. The method may include mixing plasma effluents with a gas in a first section of a chamber to form a first mixture. The method may also include flowing the first mixture to a substrate in a second section of the chamber. The first section and the second section may include nickel plated material. The method may further include reacting the first mixture with the substrate to etch a first layer selectively over a second layer. In addition, the method may include forming a second mixture including products from reacting the first mixture with the substrate.

Abstract: Processing platforms having a central transfer station with a robot and an environment having greater than or equal to about 0.1% by weight water vapor, a pre-clean chamber connected to a side of the transfer station and a batch processing chamber connected to a side of the transfer station.

Abstract: Methods of selectively removing silicon oxide are described. Exposed portions of silicon oxide and spacer material may both be present on a patterned substrate. The silicon oxide may be a native oxide formed on silicon by exposure to atmosphere. The exposed portion of spacer material may have been etched back using reactive ion etching (RIE). A portion of the exposed spacer material may have residual damage from the reactive ion etching. A self-assembled monolayer (SAM) is selectively deposited over the damaged portion of spacer material but not on the exposed silicon oxide or undamaged portions of spacer material. A subsequent gas-phase etch may then be used to selectively remove silicon oxide but not the damaged portion of the spacer material because the SAM has been found to not only preferentially adsorb on the damaged spacer but also to halt the etch rate.
