Abstract:
A semiconductor structure, integrated circuit device, and method of forming semiconductor structure are provided. In various embodiments, the semiconductor structure includes a substrate containing a high topography region and a low topography region, an outer protection wall on an outer peripheral portion of the high topography region next to the low topography region, and an anti-reflective coating over the outer protection wall, the high topography region, and the low topography region.

Claim (Index 16):
A method for forming a semiconductor structure, wherein the method comprises:\n forming a first semiconductor structure and a second semiconductor structure on a substrate, wherein the first semiconductor structure and the second semiconductor structure are apart a trench, the first semiconductor structure and the second semiconductor structure both adjoin the trench, the first semiconductor structure is higher than the second semiconductor structure, and a top surface of the first semiconductor structure and a top surface of the second semiconductor structure are both higher than a bottom of the trench; forming a hard mask over the first semiconductor structure, the second semiconductor structure, and the bottom of the trench; forming a pool-like protection structure on the hard mask covering the first semiconductor structure, wherein the pool-like protection structure encloses a periphery of the first semiconductor structure and covers a portion of a top surface of the hard mask, thereby exposing an uncovered portion of the top surface of the hard mask; forming a protection film covering the uncovered portion of the top surface of the hard mask, wherein a top surface of the protection film is lower than a top surface of the pool-like protection structure; and applying an anti-reflective coating over the pool-like protection structure, the protection film, and the second semiconductor structure, wherein the trench is filled with the anti-reflective coating.
