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 semiconductor memory device and manufacturing method, including a bit line connector and a lower electrode connector that respectively connect a bit line and a capacitor lower electrode of the device to active areas of a semiconductor substrate. The connectors are formed using a line-type self-aligned photoresist mask pattern positioned on an interlevel dielectric layer formed on the substrate, which exposes only a portion of the dielectric layer corresponding to a source region and which extends in a direction which a gate electrode extends, to provide a misalignment margin. The bit line connector and the lower electrode connector are respectively formed by one-time mask processes. A contact hole for the bit line connector in a cell area, and a contact hole for a metal wiring plug in a peripheral area are simultaneously formed, alleviating etching burden during subsequent forming of a metal wiring pad.
