    摘要: Methods and apparatus to form films on sensitive substrates while preventing damage to the sensitive substrate are provided herein. In certain embodiments, methods involve forming a bilayer film on a sensitive substrate that both protects the underlying substrate from damage and possesses desired electrical properties. Also provided are methods and apparatus for evaluating and optimizing the films, including methods to evaluate the amount of substrate damage resulting from a particular deposition process and methods to determine the minimum thickness of a protective layer. The methods and apparatus described herein may be used to deposit films on a variety of sensitive materials such as silicon, cobalt, germanium-antimony-tellerium, silicon-germanium, silicon nitride, silicon carbide, tungsten, titanium, tantalum, chromium, nickel, palladium, ruthenium, or silicon oxide.

    摘要: 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.

    摘要: High-deposition rate methods for forming transparent ashable hardmasks (AHMs) that have high plasma etch selectivity to underlying layers are provided. The methods involve placing a wafer on a powered electrode such as a powered pedestal for plasma-enhanced deposition. According to various embodiments, the deposition is run at low hydrocarbon precursor partial pressures and/or low process temperatures. Also provided are ceramic wafer pedestals with multiple electrode planes embedded with the pedestal are provided. According to various embodiments, the pedestals have multiple RF mesh electrode planes that are connected together such that all the electrode planes are at the same potential.
