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.
