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. The processing platform configured to pre-clean a substrate to remove native oxides from a first surface, form a blocking layer using a alkylsilane and selectively deposit a film. Methods of using the processing platforms and processing a plurality of wafers are also described.
Abstract:
Methods and apparatus for forming a conformal SiCON film on a surface are described. A SiCN film is formed on a substrate surface and exposed to a low temperature steam annealing process to form a film resistant to damage by rapid thermal processing or ashing. The film is treated by rapid thermal processing and then subjected to a high temperature anneal to form a film with a low dielectric constant.
Abstract:
Methods and precursors for selectively depositing a metal film on a silicon nitride surface relative to a silicon oxide surface are described. The substrate comprising both surfaces is exposed to a blocking compound to selectively block the silicon oxide surface. A metal film is then selectively deposited on the silicon nitride surface.
Abstract:
Memory devices and methods of forming memory devices are described. The memory devices comprise a substrate with at least one film stack. The film stack comprises a polysilicon layer on the substrate; a bit line metal layer on the polysilicon layer; a cap layer on the bit line metal layer; and a hardmask on the cap layer. The memory device of some embodiments includes an optional barrier metal layer on the polysilicon layer and the bit line metal layer is on the barrier metal layer. Methods of forming electronic devices are described where one or more patterns are transferred through the films of the film stack to provide the bit line of a memory device.
Abstract:
Methods for the formation of SiCN, SiCO and SiCON films comprising cyclical exposure of a substrate surface to a silicon-containing gas, a carbon-containing gas and a plasma. Some embodiments further comprise the addition of an oxidizing agent prior to at least the plasma exposure.

Methods of manufacturing memory devices are provided. The method comprises pre-cleaning a top surface of a film stack, the film stack comprising alternating layers of a first material layer and a second material layer and having one or more of a memory hole and a slit pattern opening extending through the film stack; exposing the top surface of the film stack to a growth inhibitor; selectively depositing a silicon-containing dielectric layer in a region of the film stack; and densifying the silicon-containing dielectric layer. The processing method is performed in a processing tool without breaking vacuum.
Abstract:
Methods for plasma enhanced atomic layer deposition (PEALD) of low-κ films are described. A method of depositing a film comprises exposing a substrate to a silicon precursor having the general formula (I) wherein R1, R2, R3, R4, R5, and R6 are independently selected from hydrogen (H), substituted alkyl, or unsubstituted alkyl; purging the processing chamber of the silicon precursor; exposing the substrate to a carbon monoxide (CO) plasma to form one or more of a silicon oxycarbide (SiOC) or silicon oxycarbonitride (SiOCN) film on the substrate; and purging the processing chamber.
Abstract:
Methods of manufacturing memory devices are provided. The methods improve the quality of a selectively deposited silicon-containing dielectric layer. The method comprises selectively depositing a silicon-containing dielectric layer in a recessed region of a film stack. The selectively deposited silicon-containing dielectric layer is then exposed to a high-density plasma and annealed at a temperature greater than 800 ° C. to provide a silicon-containing dielectric film having a wet etch rate of less than 4 Å/min.
