    摘要: A technique for enhancing the performance of a memory- and logic-equipped semiconductor device is provided. The semiconductor device comprises a semiconductor substrate (1), an insulating layer (19) on the semiconductor substrate (1), a plurality of contact plugs (16, 66) in the insulating layer (19), and an insulating layer (30) where capacitors (82), a plurality of contact plugs (25, 75), barrier metal layers (27, 87) and copper interconnections (29, 88) are formed. Source/drain regions (9) in the upper surface of the semiconductor substrate (1) are electrically connected to the copper interconnections (29). One of adjacent source/drain regions (59) in the upper surface of the semiconductor substrate (1) is electrically connected to the copper interconnection (88), while the other is electrically connected to the capacitor (82).

    摘要: A semiconductor substrate is arranged to have a DRAM area in which to form at a high density gate electrodes of transistors serving as DRAM components, and a peripheral circuit area in which to form at a relatively low density gate electrodes of transistors as peripheral circuit components. A resist film is formed in corresponding relation to the gate electrodes of the DRAM. After an insulating film is etched, a resist film is formed in corresponding relation to the gate electrodes of the peripheral circuits. A conductive layer is then etched while the resist film and insulating film left in the DRAM area are being used as masks, whereby the gate electrodes are formed in the DRAM area and peripheral circuit area.
