    Abstract: PURPOSE: A method for manufacturing a semiconductor memory device is provided to reduce a fabrication cost and a period of fabrication process by reducing the number of photo-lithography process. CONSTITUTION: A gate electrode(105) is formed on a semiconductor substrate(100). A junction region(106) is formed on both sides of the gate electrode(105). The first interlayer dielectric(110) is formed on the resultant. A plurality of self aligned contact pad regions(112a,112b) and a local wiring contact hole(112c) are formed by etching the first interlayer dielectric(110). The first plug(115c) is formed by burying the first conductive layer into the self aligned contact pad regions(112a,112b) and the local wiring contact hole(112c). The second interlayer dielectric(118) is formed on the resultant. A bit line contact hole(120a), a gate contact hole(120b), and a local wiring via hole(120c) are formed by etching the second interlayer dielectric(118). A bit line contact plug, a gate contact plug(130b), and the second plug(130c) are formed by burying the second conductive layer into the bit line contact hole(120a), the gate contact hole(120b), and the local wiring via hole(120c).
