Disclosed herein is a top anti-reflective coating composition which comprises a photoacid generator represented by Formula 1 below. wherein n is between 7 and 25. Since the top anti-reflective coating composition dissolves a portion of a photoacid generator present at the top of an underlying photosensitizer, particularly, upon formation of a top anti-reflective coating, it can prevent the top from being formed into a thick section. Therefore, the use of the anti-reflective coating composition enables the formation of a vertical pattern on a semiconductor device.
