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 2):
The method of  claim 1 , wherein the second oxidation condition is different from the first oxidation condition by one or more of the following: (1) an oxidation time, (2) a radio-frequency (RF) power, and (3) a substrate temperature.
