Abstract:
Embodiments are directed to a method of forming a semiconductor device and resulting structures having a hard masks for sidewall image transfer (SIT) block patterning. The method includes forming a first hard mask on a substrate. Spacers are formed on the first hard mask, and a second hard mask is formed over the spacers. The second hard mask and a portion of the first hard mask are concurrently removed by the same hard mask removal process to expose a surface of the substrate. After concurrently removing the second hard mask and portions of the first hard mask, the heights of the spacers are substantially equal.

Claim (Index 7):
The semiconductor device of  claim 4 , wherein the RIE is selective to the first plurality of spacers and the second plurality of spacers.
