Abstract: This application relates to a method of filling a gap in a three-dimensional structure over a semiconductor substrate. The method may include depositing a thin film at least on a three-dimensional structure over a substrate using at least one reaction gas activated with a first radio frequency (RF) power having a first frequency, the three dimensional structure comprising a trench and/or hole. The method may also include etching the deposited thin film using at least one etchant activated with a second RF power having a second frequency lower than the first frequency. The method may further include repeating a cycle of the depositing and the etching at least once until the trench and/or hole are filled with the thin film. According to some embodiments, a thin film having substantially free of voids and/or seams can be formed in the three-dimensional structure.

Abstract: A substrate processing method for filling a gap without seams or voids comprising: providing a substrate with a gap in a reaction chamber, pumping down the reaction chamber to a pressure at or below 5 Torr and filling the gap with a film by alternately and sequentially supplying a precursor, a reactant and a radio frequency electromagnetic radiation comprising a relatively high radio frequency component and a relatively low radio frequency component.
