    摘要: At least a laminate of a gate insulating film 6 and a gate electrode 7 and an active region 13 are formed on a silicon substrate 1, and an underlying interlayer insulating film 10 is further formed. Then, a conductor 11a connected to the gate electrode 7, and a conductor 11b that is a dummy conductor and is connected to the active region 13 are formed simultaneously on the underlying interlayer insulating film 10. Thereafter, an interlayer insulating film 12 is formed on the underlying interlayer insulating film 10 by a plasma process. At this time, charging current from a plasma 14 is emitted through the conductor 11b, which is a dummy conductor.

    摘要: A method of fabricating a semiconductor memory device on a semiconductor substrate is disclosed. A gate electrode that becomes a word line, a bit line, and a charge-storage electrode are formed in a memory cell array region of a semiconductor substrate. A capacitor insulator layer and a plate electrode are formed in that order. Then, a BPSG film is formed in the memory cell array region and in the peripheral circuit region. A resist pattern is formed on the BPSG film, leaving the memory cell array region exposed. Using the resist pattern thus formed as a mask, an etching treatment is applied to remove an upper surface portion of the BPSG film lying within the memory cell array region by a given amount. After the resist pattern is removed, the BPSG film is heated in order that it reflows to planarize.
