Abstract
A method of fabricating a semiconductor device and a fabrication system of the semiconductor device are provided. The method includes sequentially forming a film to be etched and a dielectric film and measuring a thickness of the dielectric film, forming a photoresist film on the dielectric film, performing a lithography process using the measured thickness of the dielectric film to form a photoresist film pattern, and etching the dielectric film and the film to be etched using the photoresist film pattern.
