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 1):
A semiconductor device comprising:\n a planarization layer formed on a substrate; a dielectric layer formed on the planarization layer; a hard mask formed on the dielectric layer, the hard mask patterned to expose a surface of the dielectric layer in a first region; a first plurality of spacers on the hard mask in the first region and a second plurality of spacers on the hard mask in a second region; and a gap filling layer over and between the second plurality of spacers; wherein a height of each spacer of the first plurality of spacers is substantially equal to a height of each spacer of the second plurality of spacers.
