Abstract: PURPOSE:To form a fine pattern by a method wherein on a film comprising a first substance a film comprising a second substance and a film comprising a third substance having the thickness similar to the second substance film are formed, the second substance is attached to the side wall of the third substance film by various etching means and with this side wall region used as an etching mask the first substance film is processed. CONSTITUTION:On a film 2 comprising a first substance a film 3 comprising a second substance and a film 4 comprising a third substance having the thickness similar to the film 3. After the third substance film is etched by a first etching means, a second etching means having strong sputtering is applied to the film 3 comprising the second substance so that the second substance is attached to the side wall of the film 4 comprising the third substance with thickness of 30 to 50% of etched thickness. Since the etching rate of the third substance is larger than that of the second substance in a third etching means, the second substance film on a re-attached region remains even after removal of the third substance film. With the film comprising the second substance on the re-attached region b used as a mash, a fifth etching means is used to etch the film 2 comprising the first substance. Thus a fine pattern of the first substance can be formed.
