Abstract:
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.
Abstract:
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 intermittent delivery of dopant species to the film between the cycles of adsorption and reaction.
Abstract:
A system for processing a substrate include a processing chamber including a pedestal to support a substrate and a controller configured to a) supply precursor to the processing chamber; b) purge the processing chamber; c) perform radio frequency (RF) plasma activation; d) purge the processing chamber; and e) prior to purging the processing chamber in at least one of (b) or (d), set a vacuum pressure of the processing chamber to a first predetermined pressure that is less than a vacuum pressure during at least one of (a) or (c) for a first predetermined period.
Abstract:
Methods for depositing nanolaminate protective layers over a core layer to enable deposition of high quality conformal films over the core layer for use in advanced multiple patterning schemes are provided. In certain embodiments, the methods involve depositing a thin silicon oxide or titanium oxide film using plasma-based atomic layer deposition techniques with a low high frequency radio frequency (HFRF) plasma power, followed by depositing a conformal titanium oxide film or spacer with a high HFRF plasma power.

Abstract:
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.
