Abstract:
Methods and apparatuses for spacer profile control using atomic layer deposition (ALD) in multi-patterning processes are described herein. A silicon oxide spacer is deposited over a patterned core material and a target layer of a substrate in a multi-patterning scheme. A first thickness of the silicon oxide spacer is deposited by multiple ALD cycles under a first oxidation condition that includes an oxidation time, a plasma power, and a substrate temperature. A second thickness of the silicon oxide spacer is deposited by multiple ALD cycles under a second oxidation condition, where the second oxidation condition is different than the first oxidation condition by one or more parameters. After etching the patterned core material, a resulting profile of the silicon oxide spacer is dependent at least in part on the first and second oxidation conditions.

Claim (Index 10):
The method of  claim 1 , wherein operations of depositing the first thickness of the silicon oxide layer, depositing the second thickness of the silicon oxide layer, and etching the portion of the silicon oxide layer and the patterned core material occur in the plasma chamber without introducing a vacuum break in between operations.
