Abstract: A method for forming a storage node contact hole in a semiconductor device is provided to minimize a stepped portion between a peripheral region and a cell region, to prevent the deformation of the storage node contact hole and to prevent the generation of short between a storage node contact plug and a bit line by removing selectively a hard mask without the loss of an interlayer dielectric using a high selectivity ratio between the interlayer dielectric and the hard mask. An interlayer dielectric(22) is formed on a substrate(21). A hard mask is formed on the interlayer dielectric. A storage node contact hole(25) is formed on the resultant structure by etching selectively the interlayer dielectric using the hard mask as an etch barrier. A protection layer(26) for filling the storage node contact hole is formed. The hard mask is removed from the resultant structure. At this time, an etch rate of the hard mask is higher than that of the interlayer dielectric. Then, the protection layer is removed.
