Described are methods of making silicon nitride (SiN) materials on substrates. Improved SiN films made by the methods are also included. One aspect relates to depositing chlorine (Cl)-free conformal SiN films. In some embodiments, the SiN films are Cl-free and carbon (C)-free. Another aspect relates to methods of tuning the stress and/or wet etch rate of conformal SiN films. Another aspect relates to low-temperature methods of depositing high quality conformal SiN films. In some embodiments, the methods involve using trisilylamine (TSA) as a silicon-containing precursor.

Methods of depositing a film on a substrate surface include surface mediated reactions in which a film is grown over one or more cycles of reactant adsorption and reaction. In one aspect, the method is characterized by the following operations: (a) exposing the substrate surface to a first reactant in vapor phase under conditions allowing the first reactant to adsorb onto the substrate surface; (b) exposing the substrate surface to a second reactant in vapor phase while the first reactant is adsorbed on the substrate surface; and (c) exposing the substrate surface to plasma to drive a reaction between the first and second reactants adsorbed on the substrate surface to form the film.

Described are methods of making silicon nitride (SiN) materials and other silicon-containing films, including carbon-containing and/or oxygen-containing films such as SiCN (also referred to as SiNC), SiON and SiONC films, on substrates. According to various embodiments, the methods involve electromagnetic radiation-assisted activation of one or more reactants. In certain embodiments, for example, the methods involve ultraviolet (UV) activation of vapor phase amine coreactants. The methods can be used to deposit silicon-containing films, including SiN and SiCN films, at temperatures below about 400° C.

摘要:
The present invention addresses this need by providing a method for forming transparent PECVD deposited ashable hardmasks (AHMs) that have high plasma etch selectivity to underlying layers. Methods of the invention involve depositing the AHM using dilute hydrocarbon precursor gas flows and/or low process temperatures. The AHMs produced are transparent (having absorption coefficients of less than 0.1 in certain embodiments). The AHMs also have the property of high selectivity of the hard mask film to the underlying layers for successful integration of the film, and are suitable for use with 193 nm generation and below lithography schemes wherein high selectivity of the hard mask to the underlying layers is required. The lower temperature process also allows reduction of the overall thermal budget for a wafer.

The present invention provides PECVD methods for forming stable and hermetic ashable hard masks (AHMs). The methods involve depositing AHMs using dilute hydrocarbon precursor gas flows and/or high LFRF/HFRF ratios. In certain embodiments, the AHMs are transparent and have high etch selectivities. Single and dual layer hermetic AHM stacks are also provided. According to various embodiments, the dual layer stack includes an underlying AHM layer having tunable optical properties and a hermetic cap layer.
摘要:
An electroplating system includes (a) a phosphorized anode having an average grain size of at least about 50 micrometers and (b) plating apparatus that separates the anode from the cathode and prevents most particles generated at the anode from passing to the cathode. The separation may be accomplished by interposing a microporous chemical transport barrier between the anode and cathode. The relatively few particles that are generated at the large grain phosphorized copper anode are prevented from passing into the cathode (wafer) chamber area and thereby causing a defect in the part.
