A method of fabricating a semiconductor device is provided. A plurality of target patterns is formed on a substrate. The plurality of target patterns is extended in parallel to each other along a first direction. A first mask pattern extending in the first direction and including a plurality of first openings is formed. A second mask pattern extending in a second direction crossing the first direction and including a plurality of second openings is formed. Each second opening overlaps each first opening to form an overlapped opening region. A region of the plurality of target patterns is etched through the overlapped opening region using the first mask pattern and the second mask pattern as a etch mask. The region of the plurality of target patterns is overlapped with the overlapped opening region.

Method for fabricating semiconductor device

A semiconductor device has a structure of contacts whose size and pitch are finer that those that can be produced under the resolution provided by conventional photolithography. The contact structure includes a semiconductor substrate, an interlayer insulating layer disposed on the substrate, annular spacers situated in the interlayer insulating layer, first contacts surrounded by the spacers, and a second contact buried in the interlayer insulating layer between each adjacent pair of the first spacers. The contact structure is formed by forming first contact holes in the interlayer insulating layer, forming the spacers over the sides of the first contact holes to leave second contact holes within the first contact holes, etching the interlayer insulating layer from between the spacers using the first spacers as an etch mask to form third contact holes, and filling the first and second contact holes with conductive material. In this way, the pitch of the contacts can be half that of the first contact holes.
