Abstract

A method for filling a gap in a semiconductor structure includes: forming the gap between two raised portions of the semiconductor structure, the gap having a bottom surface and two lateral surfaces each extending upwardly from the bottom surface along one of the raised portions to terminate at an upper surface of a corresponding one of the raised portions; and forming a filler element in the gap in a bottom-up manner that avoids the filler element being formed laterally.
