Abstract: The present invention discloses a method for fabricating a semiconductor device using an etch-resistant polymer. The method includes a step for the in-situ generation of a polymer layer on the exposed surfaces of a photoresist film pattern, a pad oxide film, and a hard mask layer. This polymer acts as a protective film and prevents photoresist erosion during trench etching processes and improves the etch selectivity. As a result, trench structures can be formed more easily and with improved dimensional control.
