Abstract: PURPOSE: A method for fabricating a plug of a semiconductor device is provided to easily control the thickness of a sidewall by forming the sidewall in a peri/core area before a cell plug is formed, and to reduce turn around time(TAT) and cost by maximizing step coverage between a cell area and a peripheral area. CONSTITUTION: A plurality of gate electrodes(34) and gate cap insulation layers are formed on a semiconductor substrate(31). A nitride layer(36) and the first oxide layer are sequentially formed on the substrate. The first oxide layer is etched back to form the first oxide layer sidewall on both side surfaces of the gate electrode. The first high density plasma(HDP) oxide layer(38) is formed on the peripheral area of the substrate. The first oxide layer sidewall in the cell area is selectively removed by using the first HDP oxide layer as a mask. The second oxide layer sidewall and a nitride layer sidewall are formed on both side surfaces of the gate electrode in the cell area. A polysilicon plug is formed on the substrate between the gate electrodes in the cell area. The third oxide layer is formed on the substrate to expose a part of the polysilicon plug in the cell area. The exposed polysilicon plug is selectively removed. The second HDP oxide layer(44) is formed on the substrate. The second HDP oxide layer and the third oxide layer are selectively polished and planarized by using the gate cap insulation layer as an end point.
