    • According to example embodiments of inventive concepts, a method includes forming cell patterns and insulating interlayers between the cell patterns on the substrate. An upper insulating interlayer including initial and preliminary contact holes is formed on an uppermost cell pattern. A first reflection limiting layer pattern and a first photoresist layer pattern are formed for exposing a first preliminary contact hole while covering inlet portion of the initial and preliminary contact holes. A first etching process is performed on layers under the first preliminary contact hole to expose the cell pattern at a lower position than a bottom of the first preliminary contact hole. A partial removing process of sidewall portions of the first reflection limiting layer pattern and the first photoresist layer pattern and an etching process on exposed layers through bottom portions of the preliminary contact holes are repeated for forming contact holes having different depths.

    • A method of forming a multi-floor step pattern structure includes forming a stacked structure having alternating insulating interlayers and sacrificial layers on a substrate. A first photoresist pattern is formed on the stacked structure. A first preliminary step pattern structure is formed by etching portions of the stacked structure using the first photoresist pattern as an etching mask. A passivation layer pattern is formed on upper surfaces of the first photoresist pattern and the first preliminary step pattern structure. A second photoresist pattern is formed by removing a side wall portion of the first photoresist pattern exposed by the passivation layer pattern. A second preliminary step pattern structure is formed by etching exposed insulating interlayers and underlying sacrificial layers using the second photoresist pattern as an etching mask. The above steps may be repeated on the second preliminary step pattern structure to form the multi-floor step pattern structure.
