Abstract
A method of fabricating shallow trench isolation structures. A substrate is provided and a masking layer and an oxide layer are formed respectively on the substrate. The masking layer, the oxide layer and the substrate are defined and an opening is formed within the substrate. A portion of masking layer and the oxide layer are removed and an insulating material is later formed to fill with the opening. The masking layer is removed and the shallow trench isolation structure of this invention is therefore achieved.
