Abstract
A method for fabricating semiconductor device includes the steps of: forming a gate structure on a substrate; forming a polymer block on a corner between the gate structure and the substrate; performing a cleaning process; performing an oxidation process by injecting oxygen gas under 750° C. to form a first seal layer on sidewalls of the gate structure; and forming a source/drain region adjacent to two sides of the gate structure.
