Abstract: Techniques disclosed herein include increasing pattern density for creating high-resolution contact openings, slots, trenches, and other features. A conformal spacer is applied on a bi-layer or tri-layer mandrel (multi-layer) or other relief feature.

This technique essentially cuts off or removes rounded features such as upper portions of sidewall spacers, thereby providing a spacer material with a planar top surface that can be uniformly etched and transferred to underlying layers.
