    摘要: In a DRAM having information storage capacitative elements over their corresponding bit lines BL, wiring grooves are defined in an insulating film for wire or interconnection formation, which are formed over a gage electrode serving as word lines of the DRAM. Sidewall spacers are formed on their corresponding side walls of the wiring grooves. Each bit line BL and a first layer interconnection composed of a tungsten film are formed so as to be embedded in the wiring grooves whose intervals are respectively narrowed by the sidewall spacers. The bit lines BL are respectively connected to a semiconductor substrate through connecting plugs. The bit lines BL and the connecting plugs are respectively connected to one another at the bottoms of the wiring grooves.

    摘要: In a semiconductor integrated circuit device having a dynamic type memory element (DRAM), a non-volatile memory element of FLOTOX structure and a MISFET, a dielectric film of an information storing capacitance element fo the DRAM and a tunnel insulation film of the non-volatile memory element are constituted in film thickness less than that of a gate insulation film of the MISFET. Thin dielectric film increases the charge storage quantity of the information storing capacitance element and decreases the occupation area of the DRAM. Thin tunnel insulation film increases the tunnel current quantity and decreases the information write time of the non-volatile memory element. Process of forming the dielectirc film and process of forming the tunnel insulation film are performed in the same process, thereby the manufacaturing process of the semiconductor integrated circuit device is reduced.

    摘要: There is provided a technique for improving the flatness at the surface of members embedded in a plurality of recesses without resulting in an increase in the time required for the manufacturing processes. According to this technique, the dummy patterns can be placed up to the area near the boundary BL between the element forming region DA and dummy region FA by placing the first dummy pattern DP1 of relatively wider area and the second dummy pattern DP2 of relatively small area in the dummy region FA. Thereby, the flatness of the surface of the silicon oxide film embedded within the isolation groove can be improved over the entire part of the dummy region FA. Moreover, an increase of the mask data can be controlled when the first dummy patterns DP1 occupy a relatively wide region among the dummy region FA.
