    • PURPOSE: An etch method of a reflection preventing layer of semiconductor devices is provided to selectively remove an organic reflection preventing layer by relatively delaying an etching speed of a photoresist due to a mixed N2 gas and to prevent a notching and a bridge phenomena by restraining photoresist losses. CONSTITUTION: An etched layer(12) is firstly formed on a semiconductor substrate(10). Then, an organic reflection preventing layer(14) is secondly formed on the entire surface of the resultant structure. After depositing and patterning a photoresist, a photoresist pattern(16a) is thirdly formed on the resultant structure. The organic reflection preventing layer(14) is lastly etched using the photoresist pattern(16a) as a mask. At this time, the etching gas of the organic reflection preventing layer(14) is made of an O2 gas and an N2 gas in the ratio of 1:4 or 1:10.
