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 an oxidation process 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. Preferably, the polymer block includes fluorine, bromide, or silicon.
