Abstract:
A process for depositing an antireflective film comprising silicon and nitrogen over a substrate disposed in a processing chamber, said process comprising the steps of:introducing a first process gas comprising silicon into the processing chamber at a first selected rate, said first selected rate causing said film to be deposited at less than about 2000 .ANG./minute;introducing nitrogen (N.sub.2) (into the processing chamber as both a dilutant gas and a reactant gas at a second selected rate which maintains a pressure in the processing chamber sufficient to permit a reaction including said first process gas and said nitrogen to proceed, said pressure being between about 1 torr and about 6 torr; andapplying energy to said first process gas and said nitrogen to cause said reaction to deposit said film comprising silicon and nitrogen to a desired thickness.
