Abstract: PURPOSE: A method for fabricating a contact hole of a semiconductor device is provided to form a contact hole for designing a mask while being not affected by an optical proximity effect, by patterning photoresist while using a periodical line/space pattern and twice performing a photolithography process. CONSTITUTION: An insulation layer is formed on a semiconductor substrate(21). The first photoresist(22) is applied on the insulation layer. The first photoresist is patterned in the first direction by using the first mask in which a line/space pattern is defined. The second photoresist(23) is applied on the entire surface of the semiconductor substrate including the patterned first photoresist. The second photoresist is patterned in the second direction vertical to the first direction by using the second mask in which a line/space pattern is vertically defined with respect to the line/space pattern of the first mask. The insulation layer is selectively eliminated to form a contact hole by using the patterned first and second photoresist.
