In the third step, the second inter-layer insulating film formed on an area on which the second plug is formed is etched and a conductive material is deposited on the upper thereof and patterned to form a bit line(27). A third inter-layer insulating film(28) and a nitride film(29) are sequentially formed on the upper entire surface of a resultant in which the bit line is formed. In the fourth step, the second and third inter-layer insulating films and the nitride film formed on an area on which the first and third plugs are formed are etched and a conductive material is filled to form a node contact and then a poly-silicon film and a photosensitive film are sequentially formed on the upper entire surface of a resultant in which the node contact is formed. In the fifth step, the photosensitive film is patterned so that the photosensitive film remains on the upper of the node contact and then an oxide film of a low temperature is formed on the upper entire surface of a resultant that the photosensitive film is patterned. In the sixth step, the oxide film of the low temperature is etched back to form a side wall on the side of the photosensitive film and the exposed poly-silicon film is etched using a resultant, in which the side wall is formed, as a mask and then the photosensitive film is removed and an amorphous silicon is deposited on the upper entire surface of a resultant that the photosensitive film is removed.
