    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.
